Located at 73rd Street, the Trefoil Arch is noted for its unique style and design.
This 16-foot arch was constructed in 1862 to provide a pathway from Conservatory Water to the Lake. Unlike the majority of bridges and arches in Central Park that were made from sandstone, the Trefoil Arch was built using brownstone. The arch's east and west sides each feature a different type of design. While the arch’s eastern side is gothic in style with a trefoil archway, its western side has a rounded arch. In addition, the eastern side has cast-iron railings and intricate quatrefoils on either side of the arch, while the western side simply features buttresses decorated in a floral pattern.
