Mount Gibraltar Trachyte Quarries Complex

Mount Gibraltar Trachyte Quarries Complex consists of six separate quarrying sites with exposed rock faces and remnants of past mining equipment scattered across the landscape. The sites show clear evidence of intensive stone extraction with large excavations and weathered rock formations still visible.

Quarrying operations began in 1886 and developed into a significant industry supplying stone for major construction projects across New South Wales. The site operated for a full century before closing in 1986 as economic conditions changed.

The Bowral Trachyte stone extracted here was used to build major Sydney landmarks and shaped the city's appearance. You can see today how this local stone influenced the architecture of the region.

Visitors can explore the quarry sites by walking along established heritage trails that connect multiple excavation areas. Information panels at key locations explain the geology and mining history of the place.

The trachyte stone from Mount Gibraltar has a rare rock composition found in commercial quantities at very few places worldwide. This geological feature made the quarries economically valuable and essential for twentieth-century construction projects.
