New Castle NH Real Estate

New Castle NH Waterfront Property

Surrounded by the Piscataqua River and Atlantic Ocean, New Castle is New Hampshire’s smallest geographic town at less than one-square mile with a year-round population of about 800. New Castle is a unique island community connected to the mainland by bridges. There are magnificent water views from about any point in this community of winding streets, quaint shingled cottages and antique homes.

Residents walk to the post office, sandy beaches or along the shoreline and greet each other along the way. New Castle is the home of the grand Wentworth by the Sea Hotel and adjacent Scottish link golf course. Here, the Wentworth by the Sea community offers some of the most extraordinary new homes anywhere on the Seacoast. In small enclave neighborhoods, are detached single family, dramatic waterfront homes and luxury condominiums, each beautiful built to fit seamlessly into the landscape. New Castle is a mecca for boat lovers because of the Piscataqua River-leading out to the Gulf of Maine-has the second fastest current in the United States.

With the lowest property taxes in the state, New Castle still offers an outstanding K- 6 elementary school while students move on to nearby Rye Junior High and Portsmouth High School.
