Jack Straw's Castle, on the edge of Hampstead Heath, was said to be the highest pub in London.  It was probably named after one of the leaders of the Peasants' Revolt (1381), who addressed rebels on Hampstead Heath from a hay wagon known as "Jack Straw's Castle".

Bram Stoker was a regular at the pub, as was Charles Dickens in his day.  The building they knew (pictured) suffered extensive WW2 bomb damage and the pub was rebuilt in a very different style.  It has now been shut down and converted into residential flats.
