Part of Clement Clark Moore’s former country estate, he developed and planned Chelsea after the Commissioners’ Plan of 1807-1811 cut an avenue and streets through his land. At its center is the General Theological Seminary and St. Peter’s, a country Gothic Revival church consecrated in 1832. Cushman Row, a row of Greek Revival town houses, dates to 1839-1840. Later, Italianate row houses were built. Apartment houses began being built in the 1890s, and a few modern buildings from the 1930s round out the district.
