Canada's Parliament Building (Parliament Hill) is a symbol of Ottawa and consists of three Gothic buildings. In the center of the square in front of the building, there is a Changming Fire Station built to commemorate the 100 years of Canadian founding. In addition to taking pictures outside, you must also queue up at Hill Centre across the road to get a free guided tour ticket with time to visit the interior of the building. Accompanied by a tour guide, visit the two houses of the Central District (the Senate is called the Red Chamber), the House of Representatives (the House is called the Green Hall), the marble statue of Queen Victoria, and you can also queue up to board the Peace Tower to see the city.
