Ursula von Rydingsvard

In Madison Square Park are four large sculptures by Ursula von Rydingsvard. The park is better known to some as the site of the Shake Shack, but it is quite an elegant sanctuary between 23rd and 25th Streets, a quieter cousin to the more frenetic Union Square Park. The sculptures - or "monumental vessel forms" - are so well suited to the park that they almost disappear among the mature trees like ghostly forms.

Von Rydingsvard normally works in cedar, but the centerpiece of the Madison Square Park exhibition is Damski Czepek, made of polyurethane resin. Damski Czepek evolved from the form of a bonnet, creating a concave space that you can stand in, complete with strings that meander outward.
