Coplay Cement Company Kilns

The Coplay Cement Company Kilns are nine vertical brick structures from the 1890s, each standing about 90 feet tall, that remain from a Portland cement factory. The structures show how cement was made during that era before more modern manufacturing techniques took over.

The facility was built in 1892-1893 and operated these Schoefer kilns until 1904, when more efficient rotary technology gradually replaced the older method. The company adapted to new advances to stay competitive.

The place tells the story of David Saylor and his pioneering role in American cement manufacturing. Visitors can see how the industry shaped the community and changed work for local people.

The site is located in Coplay and connects to the Ironton Rail Trail for easy access. The place has parking near the structures, making it convenient for visitors to explore on foot.

The limestone deposits in the area naturally contained all three minerals needed for cement production: lime, silica, and alumina in a single rock. This rare combination made the location economically attractive for cement manufacturing.
