Crown Heights, which was built in the 1920s and had been occupied by Rescue 2 since 1985. Parks, open spaces, and recreation Parks Just east of the Crown Heights–Utica Avenue subway station, on the border with Crown Heights, there is a park called Lincoln Terrace (also known as Arthur S. Somers Park), which slopes gently down toward the southern Brooklyn coastline. The New Lots Line transitions from a tunnel to an elevated structure within this park. The of land for Lincoln Terrace was purchased by the city in 1895–1897. In order to deter aircraft from flying through the area during World War I, parts of the park had turrets installed in "serviceable but inconspicuous locations" in 1918. Through 1935, additional land was added to the park (including land purchased from the Interborough Rapid Transit Company in 1928, which had built its New Lots Line in 1920). Streets were closed to make room for the extra parkland. The park was originally named after Abraham Lincoln, but in 1932, the western section of the park (west of Rockaway Parkway) was renamed after activist Arthur S. Somers, an area resident who had died that year. Around that time, the park and its playgrounds were refurbished. Betsy Head Park is located in a lot on the north side of Livonia Avenue bounded by Strauss Street and Thomas S. Boyland Street. Opened in 1915, it is named after Betsy Head, a rich Briton, who died in 1907. In 1936, a new Olympic-size swimming pool, one of 11 across the city, was added as part of a Works Progress Administration project. In 2008, the New York City Landmarks Preservation Commission designated the Betsy Head Play Center as the first individual city landmark in Brownsville. At Livonia Avenue and Powell Street, Livonia Park is named after Livonia, in the Baltic region in what is now Latvia and Estonia. Livonia Avenue itself is so named for the same reason. According to the New York City Department of Parks and Recreation, the park honors Livonia and its native people, the Livonians. The Livonians were never fully independent, instead being alternatively led by the Teutonic Order, Sweden, and the Russian Empire. The Kingdom of Livonia was a nominal state of Russia from 1570 to 1578 during the Livonian War, but did not actually gain independence. Eventually, the Livonians were assimilated into the larger Latvian population, keeping parts of their language
