Centennial Olympic Park, Atlanta

This park, created for the 1996 Olympic Games held in Atlanta, has 21 acres (8.5 hectares) of green space, rock gardens and artwork. The nearly 500,000 commemorative bricks that make up its main walkway were part of fund raising efforts for the Games. During scorching Atlanta summers, children frolic in the ground-level Olympic Rings, which periodically shoot streaming arcs of water in time to the seven light and music concerts put on throughout the day. Flags honoring the nations that have played host to the Olympics in the past surround the fountain.
