scheduled, operated by Isles of Scilly Skybus, to and from Land's End, Newquay, and (except in winter) Exeter. Helicopter services were operated by British International Helicopters, from Penzance Heliport; this service, which started in 1964 (then operated by BEA Helicopters), ceased at the end of October 2012. Helicopter flights resumed in 2020 with the launch of the Penzance Helicopter service. By sea, the Isles of Scilly Steamship Company provides a passenger and cargo service from Penzance, which is currently operated by the Scillonian III passenger ferry, supported by the Gry Maritha cargo vessel. The other islands are linked to St. Mary's by a network of inter-island launches. The main harbour of St Mary's (and the Isles of Scilly) is at Hugh Town, and is called St Mary's Harbour. Further slipways and small quays exist around the island, at natural harbour sites, such as at Old Town, Pendrathen, Watermill Cove, and Porthloo. RNLI There has been an RNLI lifeboat station on St Mary's since 1837. The first two lifeboats were kept in a boathouse on the town beach at Hugh Town. Following closure in 1855 the lifeboat station was re-opened in 1874 and a boathouse was built on the beach at Porth Cressa. In 1899 a new boathouse and slipway were built at Carn Thomas and the first motor boat arrived in 1919. The lifeboatmen of St Mary's have earned 26 RNLI medals for bravery, comprising one gold, nine silver and 16 bronze, the last awarded in 2004. Churches For the Anglican churches see St Mary's Church, St Mary's and St Mary's Old Church, St Mary's. John Wesley preached here on 13 September 1743. The Wesleyan Methodist Society was established in 1788 and the first chapel erected in 1790. This was replaced in 1828. The present Methodist church was built in 1899 by A.J. Trenear in Hugh Town and is part of the Isles of Scilly Methodist Circuit. Landmarks Telegraph Tower The tower on Newford Down, now known as Telegraph Tower, was built in 1814 to serve as an Admiralty Telegraph Station, but it had closed by 1816. The building then reverted to the custody of the landowner - the Duke of Leeds. In 1831 the site was taken over by the Coastguard as a subsidiary to the main station situated on the Garrison. In 1903 a wireless mast and receiving office were built nearby, and in 1908 a telegraph house
