The Mercer-Fonthill Castle Family Museum is actually a site composed of two museums and which are both dedicated to preserve and promote the collection as well as the vision and ideals of historian Henry Mercer. The site is owned and managed by the Bucks Historical Society, which succeeded in restoring both estates. The Mercer Museum, which is listed as a National Historical Landmark, was built in 1916 and currently houses over 40,000 different kinds of artifacts personally collected by H. mercer. Majority of the artifacts are during the pre-industrial era and representing sixty types of trades that include but aren?t limited to agriculture, metal and wood working, advertising, folk art, and furnishing. Some of the Mercer Museum?s most interesting displays include a balcony-suspended fire engine and full-scale gallows.

The Fonthill Museum is a part of Mercer?s six-story concrete castle, which boasts of forty-four rooms, eighteen fireplaces, and more than 200 windows of all shapes and sizes. The tiles used for the castle?s interiors are all handcrafted and a sight to behold. It?s the best place to visit to enjoy a breathtaking glimpse of Mercer?s taste in architecture.
