St Paul’s Cathedral has watched over the City of London from its highest point since 1710 and is an iconic part of the London skyline. Guests can explore the stunning interior, and tickets also include the crypt and the galleries of the dome, designed by Sir Christopher Wren. Watch out for the Stone Gallery, where you’ll get the best views from the outside of the cathedral, and the Whispering Gallery where the tiniest sound can be heard by anyone on the other side of the dome!
