The oldest purpose-built outdoor shopping plaza in America, Newkirk Plaza is home to some of the area’s longest-standing businesses, including Leon’s Barber Shop, which has been in operation for roughly 100 years. Below the plaza is the Brighton subway line, which was “sunk” below street level in 1917. Turning north up East 16th Street, the block between Newkirk and Ditmas Avenues is home to a group of 13 bungalows constructed in 1908–09 after designs by Arlington Isham.
