Thomas Marble Quarry Houses
Why it's listed
Built of locally quarried stuccoed stone near Oaklands in West Whiteland Township, these three structures are the surviving remnants of the Thomas Marble Quarry, which opened in 1833. Two identical workers' houses, each divided to serve two families, have double entrances and a shared central chimney, with plain plastered interiors and stairways rising from basement to attic. The Quarry Master's House was a banked, one-story building with a loft used as the quarry office. The quarry supplied marble for Girard College in Philadelphia, designed by Thomas U. Walter, and for the Bank of Chester County in West Chester, built 1836-37. It was worked until 1844, reopened in 1867 under steam power, and was later connected to the Chester Valley Railroad. The houses are valued for their rare survival as worker housing in a mostly agricultural township, and for their connection to a quarry whose marble was used in several important Delaware Valley buildings.
Significance in brief: The houses are regarded as examples of vernacular housing built to shelter quarry workers, a type described as rare in the agricultural township. The quarry is significant for its association with marble supplied to important buildings, including Girard College in Philadelphia, designed by Thomas U. Walter, and the Bank of Chester County in West Chester.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits.
