The Great Island - New Castle NH - Ann Cummings New Castle NH Copyright

As you can see from the sign that greets you as you drive into Newcastle NH, you’re driving onto a quaint and charming island community, dating back to the early 1600’s.  There are a good number of homes in Newcastle that date back to the 1600’s that are still being lived in.

From the narrow winding streets, you’ll see some stunning antique homes, gorgeous water views of the Piscataqua River or the back channel, and a slightly modern day view of what life might have been like back then.

New Castle was originally known as “The Great Island”, being the largest of several islands in the mouth of the Piscataqua River.  The Piscataqua River is the dividing line between New Hampshire and Maine, and has the third fastest river current in the world.

Newcastle is the smallest town in New Hampshire, covering only .8 square miles, which is roughly 512 acres or so, and the only town in NH located entirely on islands.  Surrounded by water, New Castle is connected to the ‘mainland’ via the causeway to Portsmouth and a drawbridge to Rye, both taking you over water and offering up even more delightful views of our great Seacoast here in New Hampshire.

New Castle NH- Great Island Common
The current population of New Castle NH is 1,100 residents, giving it a population density of 1,376 people per square mile.  The island residents love seaside living, and get to enjoy a wonderful ocean side park called owned by the town, “Great Island Common“.

Great Island Common is a 31 acre ocean side park, open to local residents for no charge.  Non-residents, during the summer season have access for a small charge.  What a great place for family gatherings, picnics, swimming, and more.

New Castle NH Beach - Looking out to the ocean

New Castle Beach is right next to The Common, making it a perfectly relaxing place to spend the day with friends and family.  Because it’s tucked away like it is, very few of the summer tourists that descend on the area find their way to this quiet relaxing spot of seaside serenity.

New Castle residents have their own elementary school, Maude H. Trefethen Elementary School, for the town’s children to attend.  They move on to Portsmouth for middle school and high school.  Children from kindergarten through 6th grade in New Castle attend this school.

The stunningly renovated Wentworth-by-the-Sea Hotel is located on New Castle.  This hotel is on the National Register for Historic Places, deservedly so.  The “Hotel Wentworth”, as it was originally named, was built atop a hill in 1874, and has fabulous views of the Little Harbor and the Atlantic Ocean.  The 1905 Treaty of Portsmouth, which ended the Russo-Japanese War, was negotiated here by President Theodore Roosevelt.

Coast Guard Station New Castle NH - Ann Cummings New Castle NH Copyright

A quaint quiet fishing village for most its existence, New Castle has played an important role in our country’s history.  Home to an actively operating Coast Guard Station, Newcastle is home to the historic Fort Constitution site and to the historic Fort Stark site.

Ft. William and Mary Historic Marker - New Castle NH - Ann Cummings New Castle NH Copyright
Constitution overlooks the Atlantic Ocean and the Piscataqua River, and was originally named Fort William and Mary.  This fort played a great role in the Revolutionary War.   Fort Stark was one of seven forts built to protect the Portsmouth Harbor.

Originally these forts were built to protect the colonists, but as the area’s importance in the ship-building industry grew and as the Portsmouth Naval Shipyard grew, the importance of these forts grew as well, and they all underwent major fortifications.

If you love history, be sure to check out the links to these forts, as there’s some great information in there not only about these forts, but others in the area.  The forts in the NH Seacoast area played major roles for our country.
