Peterhead Granite

Peterhead Granite was sourced from numerous quarries near the town of Peterhead, in Aberdeenshire. The stone comes from the Peterhead Granite Pluton, which formed during the later part of 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. Peterhead Granite was used locally, regionally, nationally and internationally, mainly to form masonry. Peterhead Granite is not quarried for building stone today.
