The Scottish Parliament building, opened in 2004, is one of the most discussed works of contemporary architecture in Britain. The building by Enric Miralles is deliberately complex — abstract leaf shapes, cantilevered concrete, irregular windows with a distinctive cross-section profile that appears on the MSP offices facing Canongate. It is polarising: some find it brilliant, others merely baffling. Either way, it is worth seeing up close.
Free guided tours run throughout the week when parliament is not in session, covering the debating chamber, the Garden Lobby and the MSP offices. Watching a debate from the public gallery is possible when parliament is sitting — check the parliament website for the schedule. The visitor centre has background on the building, the devolution settlement and the history of Scottish self-government.
