Griffith Quarry Museum
Complete with some of the original office furniture of the Penryn Granite Works, the Griffith Quarry Museum explains the history of a mine and a town centered not around gold, but around granite. The Griffith Quarry Museum was the office of the Penryn Granite Works, which was established by Welsh Immigrant Griffith Griffith in 1864. The surrounding 23-acre park contains ruins of the first polishing mill built in California and some of the quarry holes from which the unique Penryn granite was taken.
