The Old York Historical Society, as the Museums of Old York, was founded more than 100 years ago to preserve the history and artifacts of York, Maine. Originally referred to as Gorgeana, York is one of New England's earliest colonial settlements. It also has the distinction of being the nation's first chartered city (1641) and first incorporated city (1642). Offering 37 period room settings and several galleries housed throughout nine historic museum buildings, the Museums of Old York showcases a wealth of early New England art, architecture, and decorative arts. The exhibits focus on the stories of southern Maine's men, women, and children and the world they created and lived in from the earliest settlement in the 1600s to the present day. Historic structures include the 1834 Remick Barn, the 1750 Jefferds' Tavern, the 1745 Old Schoolhouse, the 1742 Emerson-Wilcox House, the 1719 Old Gaol, the 1747 Ramsdell House, the 1740s John Hancock Wharf, the 1867 George Marshall Store, and the 1730 Elizabeth Perkins House.

Built brick-by-brick in stages beginning in 1861 by the utopian Oneida Community (1848—1880), the 93,000-square-foot Mansion House testifies to the Community's core belief in the possibility of personal and social perfection. In plan and decoration it reflects popular architectural styles of the mid-19th century, but its large scale epitomizes the needs of a society that lived as one family with more than 300 members. Continually inhabited since 1862, the Mansion House features a museum, overnight lodging, residential apartments, the Zabroso Restaurant in the Community dining room, and banquet and meeting facilities. Century-old trees define the grounds where meandering paths lead to gardens that change with the seasons.

The 157-foot-high lighthouse is still an aid to navigation. Visitors who climb the 199 steps to the top of the lighthouse are rewarded with a panoramic view of the Cape May peninsula. The first known lighthouse at Cape May was built in 1823. By 1847 a new lighthouse was erected on a high bluff; however, due to the encroaching sea and poor building design it was eventually dismantled. Built in 1859, the current lighthouse used the original bricks of the 1847 lighthouse. Also on the site is a World War II bunker, built as part of the Harbor Defense Project of 1942.

The site offers exhibits, tours, and educational and recreational events.
