Nearest tube stop: Westminster
Just across Westminster Bridge next to the Houses of Parliament is Westminster Abbey, a grand cathedral where many luminaries from British history are interred and where coronations have been held for centuries. One such famous person who rests there there is Laurence Olivier; his ashes are buried in Poet’s Corner next to the likes of Rudyard Kipling, Thomas Hardy, Robert Browning, David Garrick and the real Henry V.
Attending mass at Westminster Abbey is free, but taking any sort of tour of the tombs and gravestones cost about 12 pounds (I’m pretty sure there is a student discount, though).
If you are a history nerd like me, you’ll probably find the admission price worth it, as well as an audio or guided tour. Aside from all of the literary and acting elite in Poet’s corner, I found the Elizabeth I and Mary Queen of Scots tombs the most interesting as one is buried on top of the other! History is fascinating.
