[1] St. Luke's Episcopal Church is located northwest of the New Haven Green, at the corner of Whalley Avenue and Sperry Street in the city's Dixwell neighborhood.

It is L-shaped in plan, with the main sanctuary oriented with its long axis perpendicular to Whalley Avenue, covered by a gabled roof.

The main entrance is at the center of the tower, set in a round-arch opening, above which is a small ornately surrounded stained glass window.

[2] The congregation of St. Luke's has its origin in one established in 1844, when the African-American membership of the city's Trinity Church on the Green separated to organize it.

At first they met in a chapel owned by Trinity, and then they purchased the building of an African-American Baptist congregation in 1852.
