Holy Trinity Protestant Episcopal Church of Harlem was founded in 1868, shortly after the close of the American Civil War. The first church, located on the corner of Fifth Avenue and 125th Street, was designed by John W. Welch and built from 1869-70. A great fire in 1888 destroyed the building, and the land was sold to Temple Israel.
A new church, on the southwest corner of Lenox Avenue and 122nd Street, was designed by William A. Potter and completed in 1888.
