Built in 1716 to 1718 for the wealthy Scottish native merchant, Captain Archibald MacPheadris and his to-be-wedded wife, Sarah Wentworth, the MacPheadris-Warner House is said to be the first urban mansion made of brick in New England. It is also the oldest of its sort in existence today, and probably one of the finest examples of such early architecture.

The mansion is composed of three stories, measuring up to 50 feet in height. Capt. MacPheadris lived in the house until his death in 1729. The house was passed on to their daughter who married the King’s Council member, Hon. Jonathan Warner.

The history of the MacPhaedris-Warner House is well explained by the antique artworks hanged around the mansion. It was declared as a National Historic Landmark in 1960.
