Salem Common Historic District is a historic district bounded roughly by St. Peter's, Bridge, and Derby Sts. and Collins Cove in Salem, Massachusetts. The Common was founded in the 17th century. Before 1800 there was no enclosing fence and livestock were free to roam across it. The present wrought iron fence around the Common was built in 1850 and has undergone restoration. The white archway that stands near the north entrance was originally a design of Samuel McIntire, but it had to be removed because of its condition. The current archway is a replica established in 1976.
