The latest renovation of the Union Square North Pavilion, Plaza & Playground is one of several that the park, one of New York City's most widely used, has undergone since it opened in 1839. The park's central lawn underwent a multiple-phase renovation in 1986 and its southern plaza was renovated in 2002. But its most recent renovation, begun in April 2008 and completed in September 2010, was to its north end.
