An annual community event designed to elevate the awareness and appreciation of public art in the city, the Nashua International Sculpture Symposium invites artists from around the world to spend three weeks in Nashua, New Hampshire, creating public art. Residents host the artists in their homes, bring meals as they work, provide transportation, and interact with the artists as they create. The completed sculptures are then placed in public places. Nashua is the only city in the United States that hosts an annual international sculpture symposium.

Begun in 2008, the Nashua International Sculpture Symposium exposes the public to different cultures and sculpture techniques to create sustainable art in the city. The symposium educates the artists about creating large-scale sculpture pieces and sculptors are chosen for their ability to contribute positively to the artistic and cultural development of Nashua, helping to improve the quality of life for both visitors and residents alike.
