beach in the cliff face to the west is the Minack Theatre, a unique open-air theatre with a unique stage backdrop of Porthcurno Bay and the Logan Rock headland. It is an unusual setting for plays staged during the summer months ranging from the traditional Shakespeare to the more contemporary. The theatre is accessible on foot from the coastal footpath by a rugged path in the cliff face or more easily by road taking the steep narrow hill leaving Porthcurno to the south towards St. Levan Church and turning left at the top. It was built virtually single-handedly by the late Rowena Cade who worked there into her eighties with the support of local labourers. Today the Rowena Cade exhibition centre, coffee shop and theatre are open to visitors for most of the year except during performances. Wireless Point A small headland to the west of the Minack Theatre called Pedn-men-an-Mere, which is now owned by The National Trust, (Cornish: 'rocky headland by the sea') is known locally as 'Wireless Point'. Here, exposed areas of granite bedrock and concrete plinths retain the preserved remains of the base and guy wire tether points of a wireless telegraphy antenna mast that was erected in 1902 by the Eastern Telegraph Company. It was thought that this was used to 'spy' on the early wireless transmissions by Marconi, a developer of radio, from the Poldhu cliff top about to the east, across Mount's Bay on the west side of the Lizard Peninsula. In those days Marconi's 'wireless telegraphy' was seen as a potential threat to the established 'cable and line telegraphy' on which the security of Porthcurno and many jobs depended. A small hut was built nearby to house the early wireless equipment and remained there for a further 21 years. The company mistakenly concluded that Marconi's efforts posed no threat to their cable business. Marconi's secretive development of the Shortwave Beam Wireless System at Poldhu would be so successful that Eastern and many other cable telegraph companies were forced into near-bankruptcy by 1928. There is a pair of large boulders near the cliff edge of which the smaller one, weighing about 5 tons, can be rocked by the weight of one adult. Porth Chapel beach Pedn-men-an-Mere overlooks the small secluded tidal beach of Porth Chapel to the west. Porth Chapel beach is named after the remains of a Christian site and medieval chapel
