About
Wentworth by the Sea is one of the most historically significant grand hotels in New England — a Victorian-era resort on Wentworth Island in New Castle, New Hampshire, where President Theodore Roosevelt hosted the 1905 Treaty of Portsmouth negotiations that ended the Russo-Japanese War and earned him the Nobel Peace Prize. The hotel was meticulously restored by Marriott and reopened in 2003 after nearly two decades of neglect. The spa features Finnish sauna, steam, and indoor/outdoor pools with views across the tidal inlet to Portsmouth harbor. The New Hampshire seacoast's rocky shoreline, lobster pounds, and historic Portsmouth city center (New Hampshire's only seaport) complete the picture. The hotel is within sight of the Isles of Shoals, where the poet Celia Thaxter kept her salon.
