Seaview Terrace, also known as the Carey Mansion, is a privately owned mansion located in Newport, Rhode Island. It was designed in the Châteauesque style based on the French chateaux of the 16th century, and completed in 1925. It was the last of the great "Summer Cottages" constructed and is the fifth-largest of Newport's mansions, after The Breakers, Ochre Court, Belcourt Castle, and Rough Point. The television show Dark Shadows used its exterior as the fictional Collinwood Mansion. Part of the main house and some of the outbuildings were leased to Salve Regina University until recently.
