George and Gretchen Wintersteen generously donated a conservation easement on the historic Clark Barn and its surrounding 2.5 acres in 2005. Although the historic Horse District is already protected by zoning, zoning regulations are subject to change. To ensure permanent protection for this historic property, the Wintersteen’s placed a conservation easement on the barn, riding arena, paddocks, and the surrounding land. This historic property is adjoins the Winthrop Polo Field, which is owned by the Aiken Land Conservancy, adding to the protected land in Aiken’s historic Horse District.
