and many mock attacks were staged. The defences included pillboxes and a petroleum warfare beach flame barrage which could be operated remotely from the tunnel. At the end of the War, although some 867 bombs fell in the (Penzance) area and 3,957 houses were damaged or destroyed, the only damage suffered by any communications equipment at Porthcurno was the destruction of an antenna when a bomb fell at Rospletha Farm, located at the top of the hill about half a mile to the west of the cable office. Submarine optical fibre cables Porthcurno's association with international telecommunications links continues to the present day. The first successors to submarine telegraph cables were submarine telephony cables of coaxial construction, some of which were landed at Porthcurno. In the last twenty years or so these have all been superseded by their very high-capacity modern descendants, those using fibre optic technology as the transmission medium instead of copper. These also have been landed at Porthcurno forming a significant link, part of the UK connection to the international telecommunications 'backbone' infrastructure. These form parts of international cable networks and include systems known as Trans-Atlantic Telephone Cable 12/13 (TAT-12/13), Gemini, Fibre-Optic Link Around the Globe (FLAG), and RIOJA. Each of these has thousands of times the capacity of all of their predecessors' cables put together. However, all of the successors of the telegraph cables today use Porthcurno merely as a shore landing-point for connecting to the national telecommunications network, passing directly via landlines buried under the local roads to a terminating station at Skewjack about inland from Porthcurno. Much of the beach and surrounding shores previously owned by Cable and Wireless was donated to the National Trust in 1993. Many of the houses built for the former Engineering College have been converted to holiday flats, making the population very seasonally dependent. Today the major industry in the area is tourism. Church of St Levan The 12th and 15th-century church of St Levan is between St Levan proper and Porthcurno, towards the end of the cul-de-sac main village road. It has medieval foundations and is adjoined by a graveyard which has two of the parish's six stone crosses and a small car park. It sits close to the coast path, lightly wooded slopes and adjoins pasture meadows. The largely unadulterated exterior has featured in the BBC drama Doctor Who.
