Nestled on the picturesque shores of New Castle, New Hampshire, the Wentworth by the Sea Resort stands as a beacon of timeless elegance and coastal charm. This historic gem, often searched as “Wentworth Marriott” due to its past affiliation, offers a perfect blend of Gilded Age grandeur and modern luxury. Whether you’re planning a romantic Wentworth oceanfront stay or exploring NH Wentworth hotels for a family getaway, this resort—and its mountain counterpart, the Wentworth Inn in Jackson—delivers unforgettable experiences. In this comprehensive guide, we’ll dive into the history, amenities, and insider tips to help you plan your ideal Wentworth NH getaway.
The Rich History of Wentworth Hotels: From Gilded Age Glory to Modern Revival
The story of Wentworth hotels in New Hampshire is steeped in American history, making “historic Wentworth Hotel” a top search term for heritage travelers. Established in 1874, the Wentworth by the Sea Resort was originally built as a grand wooden structure on the New Hampshire coast, quickly becoming a playground for the elite. Owned by brewing magnate Frank Jones from 1879, it hosted presidents, dignitaries, and even played a pivotal role in world events. In 1905, it was the site of negotiations for the Treaty of Portsmouth, ending the Russo-Japanese War—earning President Theodore Roosevelt the Nobel Peace Prize.
After decades of ownership changes, including a period under Margaret and James Barker Smith from 1946 to 1980, the resort faced demolition in the 1990s. Thanks to preservation efforts by Ocean Properties, it was meticulously restored and reopened in 2003 as a Marriott franchise, known as Wentworth by the Sea, A Marriott Hotel & Spa. This Marriott Wentworth legacy brought modern amenities while preserving Victorian towers and historic charm. However, in March 2023, it transitioned to the Opal Collection, shedding its Marriott branding but retaining its AAA Four-Diamond status and membership in Historic Hotels of America. Today, it’s ranked #12 Top Hotel in the Northeast by Condé Nast Traveler’s 2025 Readers’ Choice Awards.
Meanwhile, the Wentworth Inn in Jackson, NH, offers a boutique twist on this legacy. Built in the late 19th century, this charming 61-room inn echoes the historic Wentworth Hotel vibe with its Victorian architecture and proximity to White Mountain adventures. Though not directly affiliated, both properties share the “Wentworth” name’s aura of refined New England hospitality, making them ideal for dual-coastal-and-mountain itineraries.
