Given we’re marking the Queen’s Diamond Jubilee with a look at sites of significance to her story located in London, it’s perhaps only fitting that we take a look at the nearest royal residence outside the city.

Windsor, located as close as half an hour by train from London’s Paddington station (or around 50 minutes to an hour from Waterloo), boasts plenty to see including the historic town centre, nearby Eton, great river and country walks and, of course, Legoland. But today our attention will remain on Windsor Castle, the oldest and largest inhabited castle in the world.

There has been a fortress on this site since shortly after the Norman invasion when in about 1080 King William the Conqueror ordered it constructed on a ridge above the river bank as part of a series of defensive fortifications around London. The earth and timber Norman castle was gradually added to over the years – King Henry I (reigned 1100-1135), the first king to live here, added domestic quarters while King Henry II (reigned 1154-1189) built substantial royal apartments transforming the castle into a palace and began replacing the outer timber walls with stone fortifications as well as rebuilding the Norman Keep as the Round Tower (parts of which still date from this period). King Henry III (reigned 1216-1272) built upon and expanded his work.

But it was in the reign of King Edward III (1307-1327) that the castle was expanded enormously. This included the reconstruction of the lower ward including the rebuilding of the chapel, naming it St George’s (although the current chapel dates from the reign of King Edward IV – 1461-1470), and the reconstruction of the upper ward complete with apartments for him and his wife, Queen Phillipa, arranged around courtyards (although some of the work wasn’t completed until the reign of his successor, King Richard II – 1377-1399). It was also during King Edward III’s reign that the castle became the base for the Order of the Garter (which he created in 1348), a role it still fulfills.

Other works were ordered by successive Tudor monarchs including King Henry VIII, Queen Elizabeth I, and Queen Mary I. Parliamentary forces seized the castle during the Civil War (Oliver Cromwell did use it as his headquarters for a time) and Royalists were imprisoned here (King Charles I was in fact buried in a vault beneath St George’s Chapel after his execution having been previously imprisoned here).

The next major additions came in the reign of King Charles II (1660-1685) when the Upper Ward and State Apartments were reconstructed in baroque splendor, the latter complete with splendid murals ceiling paintings by Italian artist Antonio Verro (the murals were later destroyed but some of the ceiling paintings survive).

From the time of King William III (1689-1702), monarchs began spending more time at Hampton Court Palace but the focus returned to Windsor with King George III. He ordered a range of improvements and updates including modernising Frogmore House in the Home Park for his wife Queen Caroline (the property was subsequently used by various royals but no-one currently lives there), but many of these were stopped prematurely due to his illness. His son, King George IV, picked up where his father left off.

In the reign of Queen Victoria, Windsor became the royal family’s principal residence and was visited by heads of state including King Louis Philippe in 1844 and Emperor Napoleon III in 1855. The Queen’s husband, Prince Albert, died here on 14th December, 1861.

King Edward VII (1901-1910) and King George V (1910-1936) both had a hand in redecorating the palace and the Queen’s father, King George VI (1936-1952), was living in the Royal Lodge in Windsor Great Park when he succeeded to the throne.

In more recent times, the castle was the home to the Queen, then Princess Elizabeth and her sister Princess Margaret, for much of World War II. The castle suffered its greatest setback in recent times in 1992 when a serious fire broke out in the Queen’s Private Chapel which destroyed several rooms including the ceiling of St George’s Hall which dated from the reign of King George IV. Restoration works took five years to complete.

Today the Queen spends many private weekends at the castle while the court is officially in residence here for a month over the Easter period and during Ascot Week in June – it’s at this time that the Garter Day celebrations take place with the installation of new knights.

The Queen also hosts State Visits here with banquets held in St George’s Hall as well as what are known as a ‘sleep and dine’ in which high profile figures are invited to dinner with the Queen before being shown a special display of items from the Royal Library and then spending the night. The Royal Standard flies from the Round Tower when the Queen is in residence.

As well as touring the State Apartments, the Gallery, Queen Mary’s Dolls’ House (completed in the 1920s for Queen Mary, wife of King George V), and St George’s Chapel, visitors to the castle can experience the Changing of the Guard at 11am every day but Sundays between May and early August (and every second day after that).

• A new exhibition featuring some of London’s leading ladies of the eighteenth century opens at the National Portrait Gallery today. The First Actresses: Nell Gwyn to Sarah Siddons is the first exhibition devoted to eighteenth century actresses and features 53 portraits depicting the likes of Gwyn and Siddons as well as Lavinia Fenton, Mary Robinson and Dorothy Jordan. Highlights of the exhibition include a little known version of Joshua Reynolds’ portrait of Sarah Siddons as the “tragic muse”, William Hogarth’s The Beggar’s Opera and Thomas Gainsborough’s portraits of Giovanna Bacelli and Elizabeth Linley. The exhibition reveals the key role these women played in the celebrity culture found in London (and elsewhere) during the period. As a counterpoint, an accompanying exhibition displays photographs and paintings of some of today’s actresses. Runs until 8th January (an admission charge applies). For more information on the exhibition or the programme of accompanying events, see www.npg.org.uk.

Cemetery in Hackney and Kensal Green, a park in Hounslow and a Piccadilly property formerly used as the Naval and Military Club are among the “priority sites” listed on English Heritage’s annual Heritage At Risk Register. Released earlier this week, the register’s 10 London”risk priority sites” include London’s first metropolitan cemetery – Kensal Green (All Souls) – which dates from 1833, Gunnersbury Park in West London – featuring a large country home known as Gunnersbury Park House, it was built in 1801-28 and later remodelled, and a mansion at 94 Piccadilly – built in 1756-60 for Lord Egremont, it was later used at the Military and Naval Club and is now for sale. Others on the list include Abney Park Cemetery in Hackney – laid out in 1840, it is described as London’s most important Nonconformist cemetery, a medieval manor farm barn in Harmondsworth in London’s outer west, Tide Mill in Newham, East London, and the entire Whitechapel High Street and Stepney Green conservation areas.

Last weekend saw thousands of people make their way to rarely opened properties across London as part of Open House London. Among the properties we visited was the Middle Temple Hall, one the finest example of a 15th century hall in London (if not the UK). The hall was built in the 1560s and early 1570s – by which time the Middle Temple, one of the medieval Inns of Court (more of which we’ll be talking about in an upcoming series), had already existed for about 200 years – and the hall which the Temple currently used, that of the former Templar Knights, was starting to fall apart. The new hall was constructed under the direction of law reporter Edmund Plowden, then Treasurer of the Inn, and funded by members of the Middle Temple. In use by about 1570, Queen Elizabeth I is, according to some stories, said to have dined there many times and it was in the hall that the first performance of Shakespeare’s Twelfth Night took place. While it suffered some damage in World War II bombings, the hall still looks much as it did in the late 1500s. It remains at the centre of the Middle Temple’s collegiate and social life and it is here that members are called to the Bar. Among the notable objects inside are numerous paintings and stained glass memorials of people associated with the Inn (including Sir Walter Raleigh and numerous monarchs – from King Charles I to King Edward VII) as well as the High Table – a table made of three 29 foot long planks from a single oak, it is said to be a gift from Queen Elizabeth I – and the ‘cupboard’, a smaller table which was apparently made from the hatch cover of Sir Francis Drake’s ship, the Golden Hind. Late note: I should add that the Middle Temple Hall is not normally open to the public.

Often confused with London Bridge, Tower Bridge stands as a testament to Victorian engineering ingenuity.

The bridge – a major restoration of which was completed in March this year – was officially opened on 30th June, 1894, by the Prince and Princess of Wales (later King Edward VII and Queen Alexandra) eight years after work on a new Thames crossing commenced, driven by the need for a bridge which was more accessible to people living in East London (at the time pedestrians and vehicles were facing considerable congestions, with some being forced to wait hours before crossing the Thames).

At the time of its completion, Tower Bridge (although not universally acclaimed at the time) was the most sophisticated and largest bascule bridge ever built – the word bascule comes from the French for ‘see-saw’ and refers to the action of the bridge when it swings open. The bascules, which took only a minute to open, were initially operated by a steam-powered hydraulic system although since 1976, they have been driven by oil and electricity.

The 293 feet tall structure was built from steel and clad in Portland stone and Cornish granite to ensure it blended with the nearby tower of London. It was built with two walkways joining to two great towers at a height of 110 feet. Initially open to the elements, these were conceived as a way for people to cross the bridge while the bascules were raised open but due to a lack of use, they were closed in 1910 (they were reopened in 1982 when the first permanent exhibition took up residence at the bridge).

These days as well as providing a thoroughfare across the river for pedestrians and vehicles (and still opening for larger boats and ships from time to time although 24 hours notice is required), the bridge – which, along with four other London bridges, is maintained by the Bridge House Estates trust, a charity whose roots go back to the 11th century – houses an exhibition which tells the story of its construction. The walkways provide wonderful views down the river.

Interestingly, the iconic colors of Tower Bridge only date from 1976 when the structure was painted red, white and blue for the Queen Elizabeth II’s Silver Jubilee. Before that, the bridge was painted a chocolate brown though it was originally a greenish blue color.

One of the most interesting stories associated with Tower Bridge is that of a bus driven by Albert Gunton. On the bridge when it started opening in December 1952, he had to make the bus jump the gap – at three foot wide – to avoid the bus toppling into the river below. Passengers only suffered minor injuries and Gunton was later awarded a bravery award for his actions.

A list of times when the bridge will be lifted (this happens around 1,000 times a year) is kept on the Tower Bridge website.

WHERE: The exhibition entrance is located at the north west tower of the bridge (nearest Tube stations are Tower Hill or London Bridge); WHEN: 10am to 6.30pm (last admission 5.30pm) daily until end of September, then 9.30am to 6pm (last admission 5pm) until March; COST: £6 an adult/£4.20 concessions/£2.50 children aged 5 to 15 (under fives are free)/£12.50 for a family; WEBSITE: www.towerbridge.org.uk

PICTURE: Bunting in Regent Street ahead of the Royal Wedding tomorrow.

Ahead of the wedding of Prince William and Kate Middleton tomorrow, here’s a look at some of the more curious and interesting facts related to London’s Royal Wedding past…

The first public Royal Wedding in modern times was that of Prince Albert, Duke of York (later King George VI), and Lady Elizabeth Bowes-Lyon (later Queen Elizabeth, the Queen Mother) which took place on 26th April, 1923. Instead of being held at a royal chapel as was more usual, they were married at Westminster Abbey in a public display which was apparently staged to lift the national spirit in the aftermath of World War I.

Lady Diana Spencer (later Diana, Princess of Wales) memorably said Prince Charles’ name in the wrong order during their wedding ceremony at St Paul’s Cathedral on 29th July, 1981. Lady Diana accidentally called him Philip Charles Arthur George instead of the correct Charles Philip Arthur George.

• Queen Victoria’s extravagant wedding cake was the first to feature a model of the bride and groom on its summit (with a figure of Britannia looming over them). The two tier cake measured nine foot across and weighed 300 lbs.

While white wedding dresses had been worn for some time, it was apparently after Queen Victoria wore a white dress at her 1840 wedding that the idea spread to the masses. (Interestingly, the first documented princess to wear a white wedding dress is said to have been Philippa of England, the daughter of King Henry IV, in 1406).

The first televised Royal Wedding was that of Princess Margaret, younger sister of Queen Elizabeth II, to Antony Armstrong-Jones (Lord Snowdon) on 6th May, 1960. It attracted some 300 million viewers worldwide.

The tradition of a royal bride leaving her bouquet on the Tomb of the Unknown Warrior in Westminster Abbey was started by Queen Elizabeth, the Queen Mother. She apparently did so in tribute to her brother Fergus who had died during World War I. Princess Mary, daughter of King George V, made a similar gesture at her wedding in 1922 – she left her bouquet at the Cenotaph in Whitehall after her wedding.

One of the most scandalous Royal Weddings was that of George, Prince of Wales (later King George IV) to Princess Caroline of Brunswick on 8th April, 1795 at the Chapel Royal in St James’s Palace. Described as being “far from a love match” on the Historic Royal Palaces’ website, Prince George was said to have been drunk during the wedding and at one stage apparently even attempted to escape from the ceremony.

If the rain stays away, the newly married prince and his bride will be returning to Buckingham Palace in the 1902 State Landau. The open-topped carriage was constructed for King Edward VII’s coronation and apparently made roomy to accommodation him. The carriage was used by Prince Charles and Lady Diana when they left St Paul’s Cathedral after their 1981 wedding. If the weather it poor, it’s expected that the 1881 Glass Coach, bought for the coronation of King George V in 1911, will be used instead.

We’re nearing the end of our series on Wren’s London (next week we’ll take a final look at some of the Wren designs we’ve not yet mentioned), so this week we look at one of his lesser known (and less accessible) designs – Marlborough House.

Tucked away behind high brick walls next to St James’ Palace just off Pall Mall, Marlborough House was built for Sarah Churchill, the Duchess of Marlborough – a confidant of Queen Anne – and completed in 1711.

The duchess, who secured a lease of the site from Queen Anne, selected Sir Christopher as the architect in preference to Sir John Vanbrugh, but she later fell out with Wren and, after dismissing him, oversaw the completion of the building herself. It is believed that the design of the house was actually the work of Wren’s son, also named Christopher, although the plans were undoubtedly drawn up under Wren senior’s watchful eye.

The house, built of red Dutch bricks brought to England as ballast in troop transports, was noted for its plain design. But the walls of the central salon and staircases were decorated with scenes of battles the Duke had fought in.

The property remained in the hands of the Dukes of Marlborough until it was acquired by the Crown in 1817. The building – which was substantially extended in the mid 1800s to the designs of Sir James Pennethorne – was subsequently used by members of the royal family including Princess Charlotte (only daughter of the future King George IV) and her husband Prince Leopold (later the King of the Belgians), Queen Adelaide, widow of William IV, Edward, Prince of Wales (later Edward VII), George, Prince of Wales (later George V), King Edward VII’s widow, Queen Alexandra, and, lastly, Queen Mary, widow of  George V.

Following the death of the Queen Dowager in 1953, Queen Elizabeth II donated it for use by the Commonwealth Secretariat who still occupy the building today.
