Buckingham Palace: The State Rooms Entrance Ticket

Buckingham Palace has served as the monarch's official London residence since Queen Victoria took up occupancy in 1837, and while the King and royal family live and work elsewhere in the building year-round, nineteen of the State Rooms open to the public for a limited summer season, giving visitors a rare look at the ballroom, throne room, and picture gallery used for state occasions. The ticketed visit typically also includes access to the palace gardens, a rare public glimpse of the private grounds behind the famous railings.

With maximum scores for must-see and culture in this batch, it's one of the most in-demand tickets in London specifically because access is seasonal and limited, unlike more permanently open sights. Plan for a full two hours, and check current opening dates carefully since they vary by year.
