Lambourn /ˈlæmbɔːrn/ is a large village and civil parish in West Berkshire. It lies just north of the M4 Motorway between Swindon and Newbury, and borders Wiltshire to the west and Oxfordshire to the north. After Newmarket it is the largest centre of racehorse training in England, and is home to a rehabilitation centre for injured jockeys, an equine hospital, and several leading jockeys and trainers. To the north of the village are the prehistoric Seven Barrows and the nearby Long Barrow, and in 2004 the Lambourn Horde was found close to the village.
