Additional "major" entrances exist at the Parade Ground, on the park's south side; Parkside and Ocean Avenues, at the park's southeast corner; and Willink Hill, at Flatbush and Ocean Avenues on the eastern border. The Ocean/Parkside and Willink entrances were designed in the neoclassical style by McKim, Mead and White, and were built in the 1890s and 1900s. The Willink entrance is flanked by a pair of granite turrets, while the Ocean/Parkside entrance is located between the two portions of a curved granite colonnade. Opposite the Willink entrance, there are the Flatbush Trees, three concrete cylinders with green sheet metal canopies, installed in 1979 and redecorated in 2015.
