In the block between 113th and 114th on Lenox Avenue (also known as Malcom X Boulevard) in South Harlem is a three-story building with a light blue facade. It is smaller than its neighbors, but it makes up for it with its elegance. 73-75 Lenox Avenue has one of the few remaining cast-iron facades in South Harlem. Built in 1903, Westminster Hall has had many uses and its changes often reflected the progression of Harlem over the last century. Today it has many common features of cast-iron architecture. These include large windows and repetitive crisp details on its columns and friezes. While the historical color of the building is unknown, the building is currently painted a light blue, standing out from its surroundings. This building is significant for its architecture as well as its important role serving south Harlem as the area developed and evolved.
