The IRT Eastern Parkway Line station was built first, in 1908, the terminal of a four-stop subway extension from Lower Manhattan to Downtown Brooklyn via the Joralemon Street Tunnel. The station's control house, a grand, ornate entrance to what was then the terminal of the Interborough Rapid Transit Company's Brooklyn lines, was designed by Heins & LaFarge, who also built the Cathedral of St. John the Divine in Morningside Heights, Manhattan. This control house was listed on the National Register of Historic Places in 1980; however, the actual entrance is now removed and now serves as a skylight into the IRT station.
