This relaxing garden features grass, a koi pond, benches, and a garden, making it the perfect atmosphere to relax or stargaze. The Observatory Hill Gardens have many native and non-native organisms, including herbaceous-plant, shrub and tree species from different parts of the world. The Heyden Observatory and Gardens at Georgetown University were originally created in 1844 to study the sky, but light pollution limited the observatory's capability and caused it to officially close in 1971. It is currently used by the GU Astronomical Society as a location to discuss new developments and history in the field of astronomy and physics.
