We begin our visit to Ottawa, Canada's capital city, at the Centennial Flame, built in 1967 to commemorate its 100th birthday, and we learn of the many festivals held here each year. Located in the province of Ontario, this city's pride is Parliament Hill, a historic cluster of buildings still used for legislative sessions. Built between 1857 and 1876, some have called it the purest example of Gothic Revival architecture in the western hemisphere. Parts were gutted by fire early in the 20th century, but the original section still houses the Library of Parliament. Royal Canadian Mounted Police patrol the area, and a highlight for tourists is the changing of the guard. Rideau Canal, a National Heritage Site, is one way to access all the historic areas of the city. Built for the city's defense during WWII, it is now used for pleasure boats. In the winter it becomes the world's largest skating rink and the perfect way to get to work each day! If you prefer walking instead of a boat ride, Sparks Street is the place to visit. This pedestrian mall and outdoor market is a stroller's delight. The National Gallery of Canada is another attraction not to be missed. Established in 1880 for the country's art collection and moved to a new building in 1998, the glass tower of the new architecture rises above the skyline to create an artistic statement of its own. Another landmark is the Chateau Laurier, built in 1912 as a railroad hotel and for members of Parliament. Its elegant Art Deco decorations still fascinate the many celebrities who stay there. Our last stop is less than twenty minutes east of Ottawa, a green space just outside the city. The Mer Bleue Conservation Area is a preserved ecosystem that delights visitors. A boardwalk spans this wetlands, best known for its sphagnum bog, and in winter there are cross-country ski trails to travel.
