Deep inside Brompton Cemetery in London resides a large mausoleum.

This is the tomb of Hannah Courtoy, a wealthy woman who died in 1849. According to official records, she is interred inside this tomb along with two of her three adult daughters. However, according to local legend, the tomb also contains a working time machine. 

Before Hannah Courtoy died, she was friends with a renowned Egyptologist named Joseph Bonomi. Bonomi was convinced that he had discovered the secrets of time travel through studying Egyptian hieroglyphics. Bonomi teamed up with engineer Samuel Warner to create a time machine.

With the financial backing of Hannah Courtoy, they built their time machine and placed it inside this tomb in Brompton Cemetery where it has remained ever since. The key to the tomb has been lost and the tomb hasn’t been opened for over 100 years.
