The main attraction at this 2.6 acre site is the vertical cement kilns. The 90 foot kilns were a marked improvement over prior methods and helped make Lehigh County the center of the Portland Cement Industry at the time. Portland cement enabled construction of bridges, subways, and buildings that transformed America in the late 19th and early 20th century.
The site is on the National Register of Historic Places. The open air museum is operated as by a partnership between Lehigh County and the Lehigh County Historical Society. It is open year round.
