During the summer months MPs retreat to their constituencies and Parliament is thrown open to the public.
The tour follows the processional route taken by Her Majesty the Queen when she performs the State Opening of Parliament. The public will be led by an expert guide through the Norman Porch, the Robing Room, Royal Gallery and Prince's Chamber, before finally entering the House of Lords. Guests will be allowed to stand in the chamber itself and look around the throne, before heading out to the Central Lobby.
The tour will then take in the Member's Lobby and the House of Commons. Guests can walk around the back of the Speaker's Chair and down the centre of the room, before heading out to St. Stephen's Hall. The tour ends where it began -- in Westminster Hall, the historic chamber which witnessed the State trials of Guy Fawkes and Charles I.
Note: Photographs are not allowed outside of Westminster Hall, and you will have to go through airport-style security before they allow you into the building.
