land for 4 ploughs. There were 1 plough, 1 serf, 1 villein, 3 smallholders, 1 acre of meadow, 40 acres of pasture, 5 cattle and 25 sheep. The value of the manor was 10 shillings though it had formerly been worth 30 shillings. Until 1 April 2021 the village formed part of the civil parish of St Teath, but it was separated into its own parish in time for the election of the first Delabole Parish Council in May 2021. The parish also covers the hamlets of Treligga and Westdowns. Economy Delabole was the birthplace of the Cornwall Air Ambulance. Businesses include Delabole Quarry and Delabole wind farm, the first commercial wind farm in the UK. The Gaia Energy Centre opened on the wind farm site in 2001 as a tourist attraction. It cost £5m and was intended to attract 150,000 visitors a year. It closed after three years of opening when it only achieved one tenth of the required visitor numbers. Most of the funding for the centre came from Europe, with £300,000 grants from Objective One and SWDRA, the South West Regional Development Agency. Delabole Quarry Delabole Quarry is one of the largest slate quarries in England and has been operated continuously from the 15th-century making it the oldest working slate quarry in England. Indeed, it is reputed that slate has been quarried here since the reign of King Stephen. In the reign of Elizabeth I the five quarries on the site of the now larger pit assumed considerable importance delivering slate to Brittany and the Netherlands. In 1841 the five quarries were combined to make the Old Delabole Slate Quarry. The Old Delabole Slate Quarry Ltd was liquidated in 1977 by the company's bankers. It was run under receivership by Rio Tinto Zinc until 1999 when a local management team bought it out. In 2005, the majority shareholders bought out the entire share capital, creating a single family ownership, the first time since 1842. In 1910, 500 people were employed at the quarry but this has since been reduced to 80, the decline due to the availability of cheaper roofing materials e.g. Welsh slate or prefabricated tiles. As of 2007 only five skilled men work in the pit and the total workforce is no more than forty. Delabole Quarry was once the deepest man-made pit in the world, but this is no longer the case due to
