Pop . (Igor) 25,617 . Llanelly is a station on the South Wales section of the Great Western railway . ' The town is wholly of modern appearance . The mother-church of St Elliw, or Elli (whence the town derives its name) has been practically rebuilt (1go6), but it retains its 13th-century tower and other ancient features of the original fabric . Its situation on a broad estuary and its central position with regard to a neighbourhood rich in coal, iron and limestone, have combined to make Llanelly one of the many important industrial towns of South Wales . Anthracite and steam-coal from the collieries of the coast and along the Loughor Valley are exported from the extensive docks; and there are also large works for the smelting of copper and the manufacture of tin plates . Llanelly, though an ancient parish and a borough by prescription under a portreeve and burgesses in the old lordship of Kidwelly, remained insignificant until the industrial development in South Wales during the loth century . In 18io the combined population of Llanelly, with its four subsidiary hamlets of Berwick, Glyn, Hencoed and Westowe, only amounted to 2972; in 1840 the inhabitants of the borough hamlet alone had risen to 4173 . Llanelly is now the most populous town in Wales outside the confines of Glamorganshire . In 1832 Llanelly was added as a contributory borough to the Carmarthen parliamentary district .
