This might just be London's strangest tomb. In St. Mary's Catholic Church in Mortlake, the mausoleum of Richard Burton makes quite the visual statement. It takes the shape of a Bedouin tent and was designed around 1890 by Burton's wife, Isabel. But the weirdest feature is around the back. Ascend the stairs, and you can see inside. Here lie the coffins of Richard Burton and his wife. Now, Isabel chose this design as a nod to his life. He was an explorer and writer who traveled extensively across Asia, Africa, and the Americas. And she championed his work, even writing his biography, despite suffering from cancer. She died in 1896, but they forever lie side by side inside a tent, as if traveling the globe together.
