It’s one of London’s most famous landmarks and, having just undergone a three year, £2 million restoration, we thought it was time to take a look at the origins of the White Tower.

Now the keep of the Tower of London, the White Tower was first built by the Norman King William the Conqueror following his defeat of Saxon King Harold Godwinson and the cream of the Saxon army at the Battle of Hastings in 1066.

Following his coronation at Westminster Abbey on Christmas Day, King William then withdrew to Barking Abbey while his men built several temporary strongholds in the city to ensure it wouldn’t cause any trouble – this included an earth and timber keep standing on an artificial mound in the south-east corner of the city’s Roman-era walls.

The White Tower, a permanent structure, replaced this and although the exact date its construction started is unknown, building – under the watchful eye of Gundulf, the Bishop of Rochester, was well underway by the mid-1070s. While the labourers were English, the masons in charge of the building were Norman and then even used some Caen stone imported from William’s homeland (along with Kentish ragstone). By 1097 the tower was complete.

Primarily built as a fortress rather than for comfort, the size of the Tower was intimidating and, at 27.5 metres tall, it would have dominated the skyline for miles. Initial defences surrounding the White Tower included the Roman walls and two ditches although in later years outer walls were added to create the massive fortifications and series of towers one encounters at the site today.

The tower earned its moniker, the White Tower, from the whitewash used on its walls during the reign of King Henry II. The caps on the four turrets which stand at each corner of the tower were originally conical but were replaced with the current onion-shaped domes in the 1500s (the round tower was once home to the Royal Observatory before it moved out to Greenwich). The White Tower’s large external windows are also more modern innovations, these were added in the 1600s by Sir Christopher Wren.

The original entrance to the White Tower was on the first floor, reached by a wooden staircase (that could be removed if necessary), much as it is today while, for security reasons, the internal stone spiral staircase was placed as far from this entry as possible in the north-east turret. A stone forebuilding was later added during the reign of King Henry II but was later demolished.

Inside, accommodation for the king was provided on the second floor – it originally had a gallery above but an extra floor – still there today – was later added. Accommodation for the Tower’s constable was probably on the first floor. Both floors were divided in two – with a large hall on one side and smaller apartments on the other. These rooms now house displays on the Tower’s history – at the present these include the Royal Armouries’ exhibition ‘Power House’.

The White Tower is also home to the Chapel of St John the Evangelist which, made from Caen stone, still looks much the same as it did in Norman times. It was used by the royal family when in residence at the tower but by the reign of King Charles II had become a store for state records. These were removed in 1857. Among some of the events which took place here was the lying in state of Queen Elizabeth of York, wife to King Henry VII, after her death in 1503, and the betrothal of Queen Mary I to Philip of Spain in 1554 (by proxy, Philip was not present). Prince Charles received communion here on his 21st birthday.

Other historic events associated with the White Tower include the apparent murder in 1483 of the ‘Princes in the Tower’ – King Edward V and his younger brother, Richard, Duke of York – while legend says they were killed in the Bloody Tower, the discovery of two skeletons under stairs leading to the chapel during building works in 1674 has led some to believe that they may have been buried here.

It was also in the White Tower that King Richard II was forced to sign away his throne to King Henry IV in 1399 and it was from the White Tower that Gruffydd ap Llywelyn Fawr, the illegitimate son of  Welsh Prince Llywelyn the Great, apparently fell to his death while attempting to escape captivity in 1244.

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.
