The ruins of a 19th-century iron foundry stand here amid a babbling brook and 87 acres of preserved marshland and woodland. Scenic trails and interpretive features recount how the foundry once buzzed with activity as the original commercial hub of Cold Spring village. Its employees manufactured Civil War cannons, cannon balls, and guns, as well as cast-iron facades for SoHo warehouses and even the nation's first domestically made locomotive. Today there's also a replica
of a historic gun platform. To get here from Main Street, turn south onto Kemble Avenue and take it to the end, proceed through the gate, turn left, and follow the path to the site. The preserve is accessible from the Cold Spring Metro-North train station.
