Mount Holly is Burlington County's historic seat of government, founded by Quakers in 1677 along Rancocas Creek and serving briefly as New Jersey's revolutionary-era capital. The walkable downtown is anchored by surviving 18th- and 19th-century buildings, including the 1796 County Court House and the Burlington County Historic Prison Museum, one of the oldest continuously used prisons in the country. Housing ranges from historic homes near downtown to established residential streets and newer construction further out, drawing buyers who want genuine architectural character alongside modern conveniences. Twenty minutes from Philadelphia, Mount Holly blends small-town identity with regional accessibility.
