An Army community developed on Governors Island during the mid-20th century. The island had three chapels in addition to the movie theater, YMCA, and "officer's club". Recreation was also popular; one common sport was polo, a relic from the 19th century when travel on the island was by horseback. In 1920, a polo playing field was established on the island's Parade Ground. Though a golf course had been built in 1903 near Fort Jay, a new polo-and-golf course called the Governors Island Golf Course was built circa 1925–1926. The course was located on the grounds of Fort Jay, and was sometimes called the "world's crookedest" golf course due to its enclosed nature in a confined space. Tennis courts and swimming pools were also present on Governors Island. Different groupings of recreational areas were generally located according to military hierarchy. The number of houses of worship increased as a Roman Catholic church was built in 1942, followed by a synagogue in 1959.
