The Trustees is Massachusetts’ largest conservation and preservation organization. We are a nonprofit supported by members, friends, and donors who love the distinctive charms of the Commonwealth, and who believe in celebrating and protecting them, for everyone, forever.
Founded in 1891 to preserve some of Massachusetts’ most important and iconic landscapes and landmarks for public use and enjoyment. Today, The Trustees stewards 120+ distinctive and visually dynamic places rich in cultural, historical, and natural context. Spanning more than 27,000 acres, these places serve as welcoming and inclusive platforms for gatherings of people of all ages and diverse interests. Trustees sites welcome more than 2 million visitors annually, and spark engagement through innovative programs and initiatives.
