USA : The Storm King Museum

Storm King Art Center is a 500-acre outdoor museum located in New York’s Hudson Valley, where visitors experience large-scale sculpture and site-specific commissions under open sky.

Since 1960, Storm King has been dedicated to stewarding the hills, meadows, and forests of its site and surrounding landscape.

Building on the visionary thinking of its founders, Storm King supports artists and some of their most ambitious works.
