Located in Manhattan's Riverside Park, this circular temple was erected in 1902 in memory of the Soldiers' and Sailors' who fought for the Union during the Civil War. It is an example of the neoclassical style in architecture, a popular choice for artists associated with the City Beautiful movement. Two plinths positioned to east and west of the temple's approach list the names of prominent Union Generals and battles. It remains a significant site for military ceremony.
