The form of Park of the Laments is a square within a square, one rigid and made of limestone-filled Gabion baskets, the other soft and organic, made of indigenous, trees and shrubs. Visitors enter the work via an underground tunnel. Moving towards the light, they climb stairs that lead them above ground into the center of the park. Visitors are invited to occupy this quiet contemplative space, which Jaar describes as a refuge, a place for lamentation and purging the global atrocities of the 20th and 21st centuries.
