Their remains were first gathered and interred in 1808. In 1867 landscape architects Frederick Law Olmsted and Calvert Vaux, designers of Central Park and Prospect Park, were engaged to prepare a new design for Washington Park as well as a new crypt for the remains of the prison ship martyrs. In 1873, after development near the Brooklyn Navy Yard uncovered the remains, they were moved and re-interred in a crypt beneath a small monument. Funds were raised for a larger monument, which was designed by noted architect Stanford White. Constructed of granite, its single Doric column in height sits over the crypt at the top of a 33-step staircase. At the top of the column is an eight-ton bronze brazier, a funeral urn, by sculptor Adolph Weinman. President-elect William Howard Taft delivered the principal address when the monument was dedicated in 1908.
