The engine houses at Wheal Coates are perched precariously on 300-foot cliffs, making them one of the most photographed industrial sites in the UK.
The area contains a 'caves and arches' coastline formed by the erosion of softer rock strata against the harder granite cliffs.
The coastline is a hotspot for seal sightings, as the offshore rocks provide resting grounds for Atlantic grey seals.
Mining activity at St. Agnes dates back to the 18th century, with remnants of the 'Towanroath' shaft still visible near the cliff edge.
The shoreline at Chapel Porth is famous for its 'caverns' that are only accessible during the lowest spring tides.
St. Agnes Heritage Coast is a stretch of protected Cornish coastline defined by rugged cliffs and industrial mining heritage. The area features extensive cliff-top trails that overlook the Atlantic Ocean and sheltered coves such as Trevaunance Cove and Chapel Porth. The landscape is marked by the remains of former tin and copper mines, most notably the iconic engine house ruins at Wheal Coates. These paths are part of the South West Coast Path, offering views of dramatic geological formations and sea stacks. The geology here is primarily granite and slate, supporting diverse coastal plant life and bird species. Visitors can access various beach levels depending on the tide, though strong currents are frequent. The site serves as a preserved environment within the Cornwall Area of Outstanding Natural Beauty.
