From the air, they look like ants.

The enormous structure was Steeplechase.

Steeplechase Park was an amusement park in the Coney Island area of Brooklyn, New York created by George C. Tilyou (1862–1914) which operated from 1897 to 1964. It was the first of the three original iconic large parks built on Coney Island, the other two being Luna Park (1903) and Dreamland (1904).[1] Steeplechase was Coney Island's longest lasting park. Unlike Dreamland, which burned in a fire in 1911, and Luna Park which, despite early success, saw its profitability disappear during the Great Depression, Steeplechase had kept itself financially profitable. The Tilyou family had been able to adapt the park to the changing times, bringing in new rides and new amusements to Steeplechase such as the Parachute Jump.
