This rather spooky building is appropriately the Fort Hamilton Gate House for Greenwood Cemetery in Brooklyn. It was built by Richard M. Upjohn in 1877 along with a smaller visitors lounge directly across the entrance. Upjohn worked with his father, also named Richard Upjohn, on the main entrance to the cemetery on 5th Avenue. Upjohn the elder was also the architect of Trinity Church, while Upjohn the younger would go on to have a distinguished solo career with his crowning achievement being the Connecticut State House. Consistent across both of their works was the high Victorian Gothic style which really came into its own following the Civil War. On the facade of the gatehouse, Upjohn placed images of hourglasses as well as reliefs of different phases of life. While this might seem a touch macabre, it was very common in cemetery architecture at the time. The house served for a time as the official residence of the gatekeeper. It was landmarked on April 12th, 2016.
