Griffith Quarry Museum

Griffith Quarry Museum – Keith Sutter

The Griffith Quarry Park and Museum is located in the town of Penryn at the edge of the foothills of the Sierra Nevada Mountains. Though gold brought thousands of men to Placer County, another rock was being mined in this region: granite. The Griffith Quarry Museum was the office of the Penryn Granite Works, which was established by Welsh Immigrant Griffith Griffith in 1864. The museum contains some of the original office furniture of the Penryn Granite Works and exhibits on the granite industry, the Griffith family, and the history of the Penryn-Loomis Basin area. Interactive displays encourage visitors to build a granite wall and learn what granite is made of.

Walking trails through the 23-acre park wander around the ruins of the first polishing mill built in California and some of the quarry holes from which the unique Penryn granite was taken. Printed trail guides are available in the museum. The Griffith Quarry Museum is listed on both the California Register of Historical Resources and the National Register of Historic Places.

The Griffith Quarry Park and Museum is located at 7501 Rock Springs Road in Penryn, California.
