1. St Paul’s
First up, spend your day in the City, walking through the hustle and bustle of city workers and skyscrapers until you reach St Paul’s: a London relic that was built right after the Great Fire of London around 1675. With your London Pass you save big on entry (it’s normally £20, but for Pass owners its free) to the dome, the crypt and all the other parts fascinating parts of this magnificent building.
