Belvedere Castle, a folly in Central Park in Manhattan, New York City, USA 🇺🇸. ...

... It contains exhibit rooms and an observation deck, and since 1919, also houses the official Central Park weather station.

Belvedere Castle was designed by Frederick Law Olmsted and Calvert Vaux in 1867–1869. An architectural hybrid of Gothic and Romanesque styles, Vaux's design called for a Manhattan schist and granite structure with a corner tower with conical cap, with the existing lookout over parapet walls between them. Its name comes from belvedere, which means "beautiful view" in Italian.

It was also used in the 2011 film The Smurfs where it served as both the hiding place of the evil sorcerer Gargamel and the location of the film's final battle.
