St Agnes (Cornish: Breanek) is a small town on the north coast of Cornwall, England. Its coastal area is a part of the Cornwall Area of Outstanding Natural Beauty (AONB).
The village of St Agnes was a prehistoric and modern centre for mining of copper, tin and arsenic until the 1920s. Much of the Cornwall and West Devon Mining Landscape, a World Heritage Site, is in the parish. Tin production is still worked at the Blue Hills Tin Streams.
Leave the A30 at the Chiverton Cross roundabout and take the B3277 north-west for 5 km. There is a car park in the village, a short walk from the local amenities and the coast.
Take the train to Truro Rail Station, then the U1A bus to St Agnes.
The village can be seen on foot, with the Library public car park a convenient central location.
