The name of the station was originally intended to be Institute Park.HistoryOn October 10, 1920, three stations that were not ready to be opened with the rest of the line, at Bergen Street, Grand Army Plaza and Eastern Parkway–Brooklyn Museum, were opened.During the 1964–1965 fiscal year, the platforms at Eastern Parkway, along with those at four other stations on the Eastern Parkway Line, were lengthened to 525 feet to accommodate a ten-car train of 51-foot IRT cars.Station layoutThere are two local tracks with two side platforms. The express tracks pass underneath the station and are not visible from the platforms. A large mosaic displays Eastern Parkway and the Brooklyn Museum. On the platforms and the eastern mezzanine are abstract art paintings, created in 1991 by artist Pat Steir and collectively called the Brueghel Series. There is an emergency exit from the express level at the south end of each platform. There is an unused western mezzanine containing turnstiles and a token booth with a door hidden in the tiles; the entrance to this mezzanine has been removed on street level.
