Fonthill was begun in 1907 and mostly complete by 1912, and the Moravian tile works was built in 1911-1912.","why_significant":"The nomination argues that Mercer was a pioneer in using reinforced concrete as a building material, and that his three concrete buildings are innovative works of architecture. It also cites his decorative tiles, which brought him wide fame, and his collections of tools, folk art and books, which the museum houses. The three sites are treated as one district because they are linked through Mercer's work.","narrative":"Three reinforced-concrete sites in Doylestown, Pennsylvania, were built by Henry Chapman Mercer between 1907 and 1916: his house Fonthill, the Mercer Museum, and the Moravian Pottery and Tile Works. Fonthill was loosely modelled on medieval castles and was built with hand-mixed concrete and reinforcing iron pipe. The Mercer Museum has over 30,000 artifacts displayed in an open well with a continuous balcony, and it was dedicated on June 17, 1916. The tile works is a U-shaped building with an arcaded courtyard, and it produced handcrafted decorative tiles that Mercer sold widely. Mercer is regarded as one of the first designers to use reinforced concrete in American buildings, and as a collector of early American tools and folk art. The sites are treated together because Mercer conceived them as one body of work.","period_of_significance":"1907-1916","architect_builder":"Henry C.
