Another Circle by Aranda\Lasch  Comprising 2,800 pieces of salvaged Indiana  limestone, a 3.5-acre circle ties together three sites at Michael Van Valkenburgh Associates’ Mill Race Park—the round lake, the People Trail,  and the river. Within the circle, additional stones  are placed to create a theater, areas for games, and more.  Photo 2 of 9 in Exhibit Columbus: A New Era of Celebrating Design
