Historical site. Lots of heritage buildings, arboretum, botanical gardens, the Agriculture museum, and a lot of Agriculture and Agrifood Canada research offices and laboratories. It's a large farm in the middle of Ottawa, Dow's Lake nearby, and the Rideau canal. Very pleasant to walk, bike, or ski(winter) through. Not as accessible as other large city parks like NYC central park because it is farm.
