The Tower of London is a historic citadel and castle located on the north bank of the River Thames. 

The castle is organized into three distinct enclosures known as wards. The innermost ward contains the White Tower and represents the earliest phase of construction. Encircling the north, east, and west sides is the inner ward. The final layer is the outer ward, which encompasses the entire castle complex. 
The heart of the complex is the White Tower, a massive structure known as a keep. A keep, or donjon, is the strongest part of a medieval castle. 
Inside the White Tower, the layout included several important chambers. The upper floor featured a grand hall in the west and residential chambers in the east. St John's Chapel occupies the south-east corner of the tower. 
Throughout history, the Tower has fulfilled many different roles. It functioned as a royal residence, an armoury, and a treasury. It also housed the Royal Mint and served as a menagerie for animals. 
The Tower is also widely known for its history as a prison. During the 16th and 17th centuries, it was used to hold people who had fallen into disgrace. Notable figures held there include Elizabeth I before she became queen and Sir Walter Raleigh. This history led to the common phrase "sent to the Tower." While popular stories often focus on violence, only seven people were executed inside the castle walls before the 20th century. Most executions actually took place on Tower Hill, where 112 people were executed over a 400-year period. 
In modern times, the Tower has transitioned into a major cultural landmark. After the Second World War, repairs were made to damage caused during the Blitz. It is now the ninth most popular tourist attraction in the United Kingdom. In 2025, the site welcomed 2,817,852 visitors. The property is under the ceremonial charge of the Constable of the Tower.
