Dundee Flagstone was sourced from numerous quarries in Angus, Dundee, Kincardineshire and Perthshire. The stone consisted originally of fine sand and mud that was deposited by rivers during the early part of the Devonian Period (c. 405 million years ago), when Scotland was south of the Equator at roughly the same latitude as southern Angola is today. The stone typically breaks preferentially along parallel bedding planes, forming tabular blocks ('flags') of hard, durable stone. This building stone includes the well-known 'Carmyllie Flagstone'. Dundee Flagstone was used locally and regionally for paving, roofing, masonry and millstones, and it was used nationally and internationally for paving. Today, Dundee Flagstone is extracted for building stone at one quarry.
