The southernmost part of Central Park, below Terrace Drive, contains several children's attractions and other flagship features. It contains many of the structures built in Central Park's initial stage of construction, designed in the Victorian Gothic style. Directly facing the southeastern shore of the Lake is a bi-level hall called Bethesda Terrace, which contains an elaborate fountain on its lower level. Bethesda Terrace connects to Central Park Mall, a landscaped walkway and the only formal feature in the Greensward Plan. Near the southwestern shore of the Lake is Strawberry Fields, a memorial to John Lennon who was murdered nearby; Sheep Meadow, a lawn originally intended for use as a parade ground; and Tavern on the Green, a restaurant. The southern border of Central Park contains the "Children's District", an area that includes Heckscher Playground, the Central Park Carousel, the Ballplayers House, and the Chess and Checkers House. Wollman Rink/Victorian Gardens, the Central Park Zoo and Children's Zoo, the NYC Parks headquarters at the Arsenal, and the Pond and Hallett Nature Sanctuary are nearby.
