The Tower of London was originally built by William the Conqueror in 1078 and added on to by various other monarchs. It is comprised of the main White Tower in the center, various towers with different functions and names, as well as the Queen's House (where Anne Boleyn was imprisoned), Tower Green (where executions generally took place), St. Peter Ad Vincula, and the Norman Chapel. The Tower also holds the Crown Jewels. The Jewel Tower still holds them today and can be seen by tourists.
The Tower is best known for its prisoners and executions. Some of its most famous prisoners came from Tudor times, such as Sir Thomas More, Anne Boleyn, Katheryn Howard, Lady Jane Grey, and Robert Devereux, Earl of Essex.
The Chapel of St. Peter Ad Vincula is where many of the famous Tudor prisoners executed at the Tower were buried. Both Anne Boleyn and Katheryn Howard were executed outside the Chapel and buried near the altar. The Chapel was built by Henry VIII in 1520.
