The chapel (built around 1000) was initially located outside the walls of the Tower. It was included in the castle area during the reign of King Henry III, during the expansion of the castle. Near the chapel, there is the place of execution of many famous people, decapitated or imprisoned in the fortress. The bodies were buried underground. During the restoration of the church in 1876, the remains of Anne Boleyn and Catherine Hovard were found and identified. With an impressive epitaph, they were buried in the crypt in front of the main altar.
