Three Seacoast buildings were recently added to the New Hampshire Register of Historic Places, including two warehouses in Portsmouth and a house in Lee.

Built in 1720, the Sheafe Warehouse was designed for the efficient loading and unloading of cargo boats, particularly gundalows on the Piscataqua River. Though such buildings were once common on the Portsmouth waterfront, it is the sole survivor of its type. Relocated to Prescott Park in 1940, it’s now used as a summer art gallery.

The 205-year-old Shaw Warehouse is a rare example of a “vernacular warehouse building.” It’s one of just three remaining industrial properties in Portsmouth’s former industrial area. It, too, is located in Prescott Park and now houses offices.

The Glidden House is a mid-18th century building that was once part of a working farm at the heart of Lee’s historic town center, an area now known as Wadleigh Falls. It serves as the back wing of a circa-1820 Greek Revival house with period detailing and still retains all of its outbuildings.

Part of the N.H. Division of Historical Resources, the Register of Historic Places helps promote the significance of its listed properties, entitling them to relief from some building codes and qualification for certain grant programs.
