Open House is the capital's biggest architectural celebration and gives the general public a rare opportunity to visit over 600 buildings, old and new, across London - many of them normally closed to the public - completely free of charge.
Visitors to Lloyd's have the opportunity to visit the Underwriting Room, the Nelson collection, the 18th century Adam Room and enjoy the magnificant view of London from the Lloyd's external glass lifts.
This year Lloyd's will be participating in Open House on Saturday 21 September.
