Hayle is famed for its three miles of golden sand and the mouth of its estuary is regarded as an international quality bird-watching spot. Hayle's port developed during the industrial revolution with rival foundries at either end of the town playing part in its rapid growth. The Cornish Copper Company was originally founded in 1756 and Harvey & Co in 1779. Hayle played an important role in assisting the mining industry and had a global reputation for steam engine manufacturing. Today Hayle is recognised as being part of the UNESCO Cornwall and East Devon Mining Landscape World Heritage site.
