Burlington County Prison Museum

The Burlington County Prison Museum is a National Historic Landmark located in historic Mount Holly. Designed by Robert Mills, one of America ‘s first native-born and trained architects, the Burlington County Prison was completed in 1811. One of Robert Mills’ first designs as an independent architect, the interior vaulted ceilings of poured concrete and brick and stone construction made the building virtually fireproof. In fact, it was so well constructed that it remained in constant use until 1965.
