Parliament Hill, overlooking the city of Ottawa, is composed of three buildings that form a spectacular neo-Gothic complex. The buildings were built between 1874 and 1878, and later extended. The three buildings form the Centre Block, with the famous Peace Tower, which houses the clock, that houses the House of Commons and the Senate, as well as the library, which is well worth a visit. The East Block houses the offices of the Canadian Prime Minister, and the West Block houses the offices of parliamentarians. There are guided tours in Spanish, past which you'll see the Queen of England's sceptre.
