Wards Island Bridge

On June 28, 1880, a boiler aboard the steamboat Seawanhaka exploded while the boat was in the East River near Wards Island, New York City, setting the boat on fire and resulting in the deaths of 24 to 35 people. A coroner's jury found that although the boiler had passed inspection the prior March and should have been in good working condition, the loss of life was exacerbated by the poor discipline of the boat crew following the explosion.

Metropolitan Park is a former baseball ground located in East Harlem, Manhattan, New York. The ground was the part-time home to the New York Metropolitans of the American Association in 1884. The wooden ballpark was built a few blocks east and south from their first home, the original Polo Grounds, on a piece of land bounded by 109th Street (north), the Harlem River (east), 107th Street (south), and First Avenue (west). It was built a block east and north of the site of the Red House hotel and grounds, which had hosted trotting, cricket and baseball from 1833 until its demise in about 1867. The park had been built on a former dumping ground, a fact which contributed to its quick demise. It also suffered from the various swamp-related unpleasantries, such as mosquitoes, which had led to the shutdown of the Red House grounds. The Mets played their first game at Metropolitan Park on May 13, 1884, amid a degree of publicity. However, the park proved unsatisfactory, and was soon labeled "The Dump" by players and other observers (especially sports reporters working for the Brooklyn Eagle). The Mets returned to the Polo Grounds for games starting on July 17, 1884, except when the New York Giants were playing at home. The final Mets game played at Metropolitan Park was on August 23, 1884. The Mets then returned to their original Polo Grounds venue, in time to win the American Association pennant. The park continued to be used for occasional amateur baseball and football for a year or two after the Mets abandoned it. The block is now occupied by a complex of residential, commercial and school buildings.

The 1199 Plaza is a housing project in East Harlem. Located on First Avenue, on the western bank of the East River, the 1199 Plaza consists of four 31-story towers, joined by mid-rise units which extend toward the riverbank. 1199 Plaza opened in 1974, as a low-to-middle income housing project. The 1199 Plaza traces its origin to the 1199 union, which consisted mainly of female lower-income hospital workers. The 1199 union members wanted housing that was safe, affordable, and socially inclusive. Hodne/Stageberg Partners, Inc served as the architects of the project, while Ruberoid supplied building materials. In the 1990s, the 1199 Plaza began offering housing for non-HUD applicants. A new title, East River Landing, was adopted. The 1199 Plaza has thus become a hybrid project, housing both middle-income and higher-income applicants, in addition to poorer residents. The 1199 Plaza has been described as a "city within a city", owing to its sheer scale and unique design.

The land for the park was acquired starting in 1897. Though the park opened in 1902, the first recreational facilities did not open until 1905. The pool and bathhouse was designed by Stanley C.

The pool was extensively refurbished in 1992, followed by the park in 1994.
