Its construction began in 1066. at the time of the Norman Conquest of England. William the conqueror in 1078, had built the White Tower which gave its name to the castle. As early as 1100, it was used as a prison while he served as a royal residence and grand palace. There were several phases of expansion, but it was mainly formed by several buildings surrounded by two concentric defensive walls and a moat. The Tower served as an armory, a menagerie, a treasury, welcomed the Royal Mint, the archives and the British Crown jewels. 112 people were executed there over a period of 400 years at the north of the tower. During the two world wars the tower was used as a prison again and 12 more executions took place. The tower has been repaired after World War II and was reopened to the public, being classified in the world heritage of the UNESCO. The tower, which controlled traffic on the Thames consists of three walls. It is a place of essential interest for millions of tourists who visit the city.
If you buy the ticket on Internet, you will pay a little less than if you would do on the spot. It will be good for a week from the date of purchase. You will be also asked to make a contribution for repairs of the place and its maintenance as the site receives nothing from the authorities; it is an organization, Historic Royal Palaces Enterprises Ltd, that operates only with what they get with the visit of tourists and their donations. They deal also with other historical sites.
You can also rent audio-guides in different languages.
The site has 5 shops that offer different products and there are also cafes and restaurants to enjoy a full day.
