Capitol Hill refers to an area centered on the Capitol. It is also a symbol of Ottawa and even Canada. In the middle of the vast lawn in front of the Capitol Building, there is an unextinguished fire called "Centenial Flame", which has been burning since July 1, 1967, and has been burning until now, and the reason for "water and fire are not allowed" does not apply here, because "unextinguished fire" is burning on the water. The water from the fire is warm all year round. The Capitol is the central symbol of Canada, the flag of maple leaves flying in the wind on the bell tower, and a series of Gothic buildings with stone bronze roofs on the Ottawa River stand firm, symbolizing the unyielding spirit of the Canadian nation. There is also an observatory on the Peace Tower, which overlooks Ottawa, and oil lamps will be lit during the meeting of the Parliament Building.
