Twenty-nine sculptures have been erected within Central Park's boundaries.[370][381][382] Most of the sculptures were not part of the Greensward Plan, but were nevertheless included to placate wealthy donors when appreciation of art increased in the late 19th century.[153][383][384] Though Vaux and Mould proposed 26 statues in the Terrace in 1862, these were eliminated because they were too expensive.[383] More sculptures were added through the late 19th century, and by 1890s, there were 24 in the park.[385]
