Prince of Wales Slate Quarry, Trewarmett

Prince of Wales Quarry near Trewarmett opened in 1871 but was only worked for just over 20 years., extracting blue slate from the Upper Devonian Penpethy Beds. The building housed the only beam engine in this part of Cornwall. It drove a wire ropeway that hauled the quarried slate and pumped water out of the quarry pit. When installed in July 1871 it cost �1,590. The beam engine is long gone but the engine house was well restored in 1973 by local effort. In 2015 the 45 acre site was sold at auction for �81,000. A circular path leads through the old slate tips, past the quarry pit (now a lake with a small waterfall) and up to the engine house. From the parking area head uphill, through a gate and shortly fork to climb through the slate tips. Beyond a flight of steps, the path ends in a platform which overlooks a waterfall and the lake but your view may be obscured by growth. Climb 59 steps to the top at a grassy platform above the engine house. There are great views down the valley to Dennis Point and Gull Rock, and over the quarry pit and spoil tips. For the best photographic view of the engine house, with the sea and Gull Rock beyond, go left uphill at the engine house up to about 650 feet. To return, facing out from the engine house doorway, take the narrow path to the left, down shallow slate steps and through scrub.
