The Moravian Pottery and Tile Works, a National Historic Landmark, is maintained as a "working history" museum by Pennsylvania's County of Bucks, Department of Parks and Recreation. Handmade tiles are still produced in a manner similar to that developed by the pottery's founder and builder, Henry Chapman Mercer (1856-1930). Mercer was a major proponent of the Arts & Crafts Movement in America. He directed the work at the pottery from 1898 until his death in 1930.
At first sight, the building resembles one of Antoni Gaudi's structures, with curves and tiles set into the stucco, with towers rising above the roof line. You can tour the factory for $3.50 and the gift shop sells tile samples.
Not far from Lambertville located on 394 Route 31 in West Amwell, NJ is Pine Creek Miniature Golf. It is my favorite miniature golf course, actually 2 courses. Beautiful landscaping and large course. Their website is www.pinecreekgolf.com
