Some can be found among other historic attractions: Chateau-sur-Mer, for example, stands among a cluster of opulent 19th-century mansions in Newport, R.I., while the Armory of the 1st Corps of Cadets is in the heart of Boston’s Back Bay. Some are destinations in themselves. Wilson Castle in the Green Mountains of Vermont and Castle in the Clouds in New Hampshire’s Ossipee Mountains are just two. Camden, Maine, boasts two castles: an observation tower on top of Mount Battie and a seaside bed-and-breakfast modeled on several different European castles.
All the castles on our list are open to the public, if only seasonally. Some are house museums. Some are bed and breakfasts or hotels. Some can simply be climbed. Many can be rented for weddings, conferences or parties.
