Fonthill startles you with it's appearance. It is like a touch of Europe dropped into a small Pennsylvania town. Henry Mercer, a renaissance man, built his version of a European castle out of poured concrete. The guided tour merely touches on the unique style and appearance of this amazing structure. The nooks and crannies, the concrete dressers, the wealth of hidden staircases all provide a mysterious and enchanting experience. This is a must visit for Pennsylvania.
