Unlike limestone, granite was slow to appear on the architectural stone market. It was not until railway construction began in the mid-19th century that industrial production of granite began. Before that time, known deposits were considered to be too far from the Montréal and Québec consumer areas. For a long time, fieldstone, with its rounded shape, was used to build fireproof houses. It came mainly from fragments detached from outcrops of Grenville Province rock and transported during glacial periods (Maurice, 1955)
