Methleigh was the site of a fair and annual market from the year 1066.[1][2] After the Norman Conquest, the Bishop of Exeter held the manor of Methleigh, but the Earl of Cornwall possessed the right to hold the fair. At the time of the Domesday Survey there were 15 acres (6.1 ha) of arable land, 40 acres (16 ha) of pasture and 60 acres (24 ha) of underbrush. The population consisted of 15 villeins, 4 smallholders and 3 serfs.[3]

Until 1844 Porthleven was within the parish of Sithney. The parish Church of St Bartholomew was built in 1842. The name Porthleven is probably connected with St Elwen or Elwyn, whose chapel existed here before 1270. It was rebuilt about 1510, but destroyed in 1549. There were also chapels at Higher Penrose and Lanner Veor (the latter founded in 1377) and a holy well at Venton-Vedna.[4] The Vicar of Porthleven in the 1850s was the Rev. Thomas Lockyer Williams, a Tractarian who introduced practices into the parish which provoked dislike in the Rev. Canon John Rogers of Penrose, Rector of Mawnan and a canon of Exeter.[5]

For local-government purposes, Porthleven was included within the nearby town of Helston, until many years of growth gained it a town council of its own. Its population at the United Kingdom Census 2001 was 3,190.[6]

Porthleven's most recognisable building is the Bickford-Smith Institute next to the pier and harbour entrance. It was built on the site of the old Fisherman's Arms and was opened on 16 December 1884. The clock tower on the west corner is 70 feet (21 m) high. The building originally had a reading room, a committee room, a curator's living room and two bedrooms.[7] The Institute was grade II listed on 18 March 1991 and currently houses the town council and a snooker club.[8] It featured (along with various other scenes from the town) as the incident room in an episode of the TV detective series Wycliffe. A picture of the building against a large breaking wave sometimes appears in the background of BBC UK weather forecasts, particularly when windy conditions and rough seas are expected. The Institute has a plaque to Guy Gibson VC, leader of the Dambuster Raid, on the wall facing the harbour. Gibson was born in India, but saw Porthleven – his mother's home town, where his parents were married – as a home town as well. He visited there while on leave during the war, sometimes attending the Porthleven Methodist Church. His name is marked on the community's war memorial (he was killed in 1944) and a street (Gibson Way) is named after him.[9]

The harbour  Part of Porthleven's boat building history

William Cookworthy acquired leases on the Tregonning Hill quarries and shipped china clay to his porcelain factory in Plymouth.[10] In 1826, 150 tons of china stone and 30 tons of china clay were exported, and in 1838, 500 tons of china stone. By 1876, 970 tons were exported and in 1883, 1002 tons.[11][12] Granite was also exported, from the quarries at Coverack Bridges and Sithney.[13]

Fifty-two fishing boats were built between 1877 and 1883, employing at times up to twenty people. They ranged in length from 22 feet (6.7 m) to 55 feet (17 m) and were built not only for Mount's Bay ports, but for others in the UK and in South Africa.[14]

Overnight on 12–13 December 1978, Police Constables Joseph James Childs and Martin Ross Reid of Devon and Cornwall Police were killed when their patrol car was swept into the harbour during a heavy storm. A stone memorial was erected on the south-facing harbour wall.[15]

Lifeboat

Due to the prevailing westerly winds, it was easy for a ship under sail to be trapped in Mount's Bay and wrecked nearby. The Royal National Lifeboat Institution stationed a lifeboat at Porthleven in 1863. A boat house was built at Breageside, from where the boat was taken to the water on a carriage. The Agar Robartes was replaced by the Charles Henry Wright (named after the donor) in November 1882.[16] A boat house on the west side of the harbour entrance was opened in 1894, with a slipway to ease launching. The station was closed in 1929, as the neighbouring stations at The Lizard and Penlee had been equipped with motor lifeboats that could cover the whole bay. The slipway was dismantled and the boat house used as a store for a while. It has since become the Shipwreck Centre museum.[17]
