Towan (from Cornish: Tewyn, meaning "sand dune") is found in many placenames in Cornwall (Porthtowan for example). However, The Towans usually refers to the three-mile (5 km) stretch of coastal dunes which extends north east from the estuary of the River Hayle (at ) to Gwithian beach (at ) with a midpoint near Upton (at Coordinates: ).
Although 'The Towans' refers to the whole stretch, individual areas of the dunes have their own identities. Those named by Ordnance Survey on its mapping are (from southwest to northeast) Hayle Towans, Riviere Towans, Mexico Towans, Common Towans, Phillack Towans, Upton Towans and Gwithian Towans.
The Towans are bounded to the southeast by Phillack village and the B3301 Hayle to Portreath road; to the northwest, the dunes face St Ives Bay across an intertidal beach. Substantial areas of The Towans rise more than 50 metres (160 ft) above sea level, the highest point being 72 metres (236 ft) at Phillack Towans.
The southern half of The Towans is in Hayle civil parish and the northern half in Gwinear-Gwithian civil parish. The southern half was in Phillack parish until 1935 when Hayle parish absorbed Phillack.
Gwithian to Mexico Towans SSSI
Much of the area falls within the Gwithian to Mexico Towans SSSI (Site of Special Scientific Interest), noted for both its geological and biological interest. Two areas of the site are also Local Nature Reserves. Upton Towans is owned by the Cornwall Wildlife Trust. It is a habitat of sand dune and grassland is suited to a variety of wildlife and plants including the pyramidal orchid, the glow worm, the silver-studded blue butterfly, and the skylark. Species in Gwithian Towans Local Nature Reserve include skylarks and adders.
Gwithian Towans cover the site of a Bronze Age farm which has been excavated although no remains are visible.
Electricity transmission lines
- For more detailed information, see Hayle Power Station
In 1910, a coal-fired power station was built on the northern flank of Hayle Towans beside the mouth of the River Hayle. The station was in use from 1910 until it closed in 1973. The buildings were demolished soon after closure but the station's legacy can still be seen in the overhead transmission lines which cross the dunes, particularly at the southern section of The Towans (see photo).
National Explosives Works
Upton Towans is the site of the National Explosives Works which was established in 1888 to supply explosives to the local mines. The dunes were flattened and small enclosures made to house individual buildings for the manufacture of the explosives. The enclosures were built to avoid chain reactions when an explosion occurred and although overgrown with vegetation, are still clearly seen today as is the network of single–track railways. On one occasion an explosion occurred in a nitroglycerine plant which broke windows in St Ives and, it was said, was heard on Dartmoor. During the First World War 1800 people were employed and the works supplied cordite to the Royal Navy. The company went into voluntary liquidation in 1919 and closed in 1920 but the storage of explosives continued until the 1960s. The site is now part of the Upton Towans Nature Reserve.
