Dr. Henry C. Mercer had it built in 1912 as a replacement for his earlier works, Aldie, which burned.","why_significant":"The nomination argues the building is significant for its founder, its structure, and its product. It cites Mercer's work in anthropology and archeology and his collection of pre-industrial Pennsylvania crafts, the premier industrial use of reinforced concrete, its adaptation of California mission church forms, and tiles that won awards.","narrative":"Built in 1912 in Doylestown, Bucks County, the Moravian Pottery and Tile Works is a U-shaped reinforced concrete factory arranged around an open courtyard. Dr. Henry C. Mercer directed its construction as a replacement for his earlier works, Aldie, which burned. He chose concrete for fireproofing, following the example of his own home, Fonthill. The exterior borrows features from several Southern California mission churches, including bell tower and cornice elements from Santa Barbara and San Juan Capistrano, while the interior mixes English manor house fan windows with Latin inscriptions. The plant has five kilns and was built in tiers. Mercer, an anthropologist and archeologist, founded it to produce ornamental tiles after finding the local clay unsuitable for pottery. The works is significant for its early industrial use of reinforced concrete, its architecture, and its tiles, which won a gold medal at the 1904 St. Louis Exposition. It later became a museum operated by the Bucks County Historical Society.","period_of_significance":"1912","architect_builder":null,"architectural_style":"Adaptation of California Mission Church style","criteria":[],"status_note":"Currently open as a museum illustrating Mercer's tile-making techniques and wares.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.035128-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/72001098.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72001098/c78e5e031c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72001098/c78e5e031c-1600.webp","licence":"CC BY-SA 2.5","author":null,"credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:MonorovianTileWorks.jpg\" rel=\"noopener\">Unknown author</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.5\" rel=\"license noopener\">CC BY-SA 2.5</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:MonorovianTileWorks.jpg"},"district":{"nrhp_refnum":"85002366","name":"Fonthill, Mercer Museum and Moravian Pottery and Tile Works","url":"https://nationalhistoricalregister.com/districts/pennsylvania/fonthill-mercer-museum-and-moravian-pottery-and-tile-works-85002366/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995282","wikipedia":"https://en.wikipedia.org/wiki/Moravian_Pottery_and_Tile_Works","wikidata":"https://www.wikidata.org/wiki/Q6909350"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/moravian-pottery-and-tile-works-72001098/"}
