About International Sculpture Day
International Sculpture Day (ISDay) is a worldwide celebration of sculpture organized by the International Sculpture Center (ISC). ISC states that the official observance occurs on the last Saturday of April each year.
Participation can range from viewing sculpture and visiting exhibitions to artist talks, studio events and workshops. Individual venues and hosts set their own admission, registration, accessibility, photography and safety rules.
Why International Sculpture Day matters
ISDay is intended to advance the creation and understanding of sculpture and to connect artists, institutions and audiences around the medium.
The observance is broad enough for public art, museum collections, studios and educational programs, but taking part does not override copyright, property, venue or workshop-safety requirements.
