Ottawa Marriott Hotel

The Ottawa Marriott Hotel (formerly a Holiday Inn, then a Radisson Hotel) is a hotel located in Ottawa, Ontario, Canada, on the north-west corner of the intersection of Queen Street and Kent Street. Upon its construction in 1972, it was the tallest building in Ottawa but as of 2006 it was the sixth tallest.

The Ottawa Marriott Hotel located in central Ottawa and is walking distance from the Parliament Buildings, the Rideau Canal, the Ottawa Convention Centre and the National Gallery of Canada. The hotel comprises 480 guestrooms, 26,000 sq ft (2,400 m2) of meeting space, a fitness centre, indoor pool and children's activity area.

In 2010, the Ottawa Marriott underwent significant renovations to the main floor. Merlot Rooftop Grill closed and re-opened as Summit, a private event space. Summit remains the only revolving room in Ottawa, rotating at a rate of approximately one revolution per two hours. The main floor renovations included closing Cafe Toulouse, their street-level restaurant and re-opening as "spin" Kitchen & Bar.
