The museum exhibits more than 90 works from 27 countries, including Armenia, Belarus, Canada, Croatia, Cyprus, Egypt, France, Finland, Germany, Great Britain, Greece, Hungary, Ireland, Japan, Lithuania, Mexico, Moldova, the Netherlands, Peru, Poland, Russia, the United States, and Venezuela.

The collection includes large-scale works by the contemporary artists Magdalena Abakanowicz, Sol LeWitt, Ales Vesely and Dennis Oppenheim,[1] among others.

All exhibits weight about 1,000 tons – so much stone, wood, concrete and other materials were used to create the museum in the open air.

The contribution of a work by the American conceptual artist Dennis Oppenheim in 1996 excited international interest in the project.

Gintaras Karosas continues to be involved in new contributions: the location of each piece is chosen to harmonize with the site's water features, its surrounding trees, shrubs, and flowers, and its daily patterning of lights and shadows.
