Parliament Hill is the symbol of Ottawa. It consists of three Gothic buildings. In the center of the square in front of the building is a bright platform built to commemorate the centenary of the founding of Canada. In addition to taking pictures outside, you must also go to Hill Center across the street to get free guided tour tickets, which have time to visit the interior of the building. Accompanied by tour guides, they visited the Senate (Senate called Red Chamber), the House of Representatives (House of Representatives called Green Chamber), the marble statues of Queen Victoria in the Central District, and queued up to Peace Tower to get a bird's eye view of the city.
