The Peace Tower is the tallest Gothic building on the axis of the Capitol Building. It is exquisite and tall with the Canadian Maple Leaf Flag flying on it. We were going to meet the elderly people gathering in front of the tower in pursuit of rights and interests, speaking and shouting slogans in a very orderly manner. If you want to visit the Capitol Building and climb the tower, you need to go to Heal Center across the street from the Capitol Building to get free tickets. The ticket we got is Center Block guided tour. Then you can go through the security check at the time on the ticket. It's amazing that such a high-level place can be visited free of charge, although there is no occasional meeting with parliamentarians or anything. The windows of the tower are as beautiful as some churches. You can also take the elevator to the top of the tower to have a bird's eye view of the whole city and the Ottawa River in the green background!
