Ross of Mull Granite was sourced from a cluster of quarries at the west end of Ross of Mull, on the island of Mull in Argyllshire. The stone comes from the Ross of Mull Granite Pluton, which formed during the Silurian Period (c. 425 million years ago) when Scotland was south of the Equator at roughly the same latitude as northern Angola is today. Ross of Mull Granite was used locally, regionally, nationally and internationally, mainly to form masonry. Ross of Mull Granite is not quarried for building stone today.
