About Wentworth by the Sea, a Historic Gem Among New Castle Hotels
Since 1874, Wentworth by the Sea Hotel & Spa has stood as beacon of elegance among the grand Portsmouth, New Hampshire hotels that once graced the coastline. Our waterfront enclave boasts an illustrious history, having hosted social, business and political leaders from around the globe. After an extensive $30 million restoration, the Wentworth has returned to its former grandeur and became a premier Marriott Hotel & Spa in the spring of 2003.
Today, our award-winning retreat continues its legacy as the grandest of New Castle hotels, providing guests with 161 guest rooms and suites, exceptional dining, and a host of resort-style amenities including a full-service spa, and both indoor and outdoor swimming pools. Stroll through our historic gardens or enjoy a friendly match on our tennis court. Guests arriving at our coastal resort by sea can even take advantage of the resort’s 170-slip marina.
Wentworth by the Sea is also New Hampshire's premier destination for meetings, conferences and romantic Portsmouth weddings. Choose from over 10,000 square feet of enchanting event space, including three beautifully-restored ballrooms, a sophisticated Executive Boardroom and pre-function space overlooking the ocean. At Wentworth by the Sea, our seasoned staff and extensive event services will delight every guest on your list.
