The ancient parish of Lyng included a Saxon burh, now occupied by the village of East Lyng, and the Isle of Athelney to the E. Athelney abbey was founded by King Alfred in 888, and the rest of Lyng was added to the abbey’s holdings by Athelstan in 937. Lyng church was described as a chapel in 1291, when it was presumably an outpost of the abbey church, staffed by the monks. A vicarage was ordained here by 1348, and the advowson remained with the abbey until the Dissolution. In 1086 Lyng was held by the Benedictine abbey of Athelney, and it consisted then of just 1 hide of ploughland, 12 acres of meadow and 50 acres of woodland.
A weekly market was granted by Henry III to the prior and convent of Athelney, to be held at Lyng manor, in 1267, but this had ceased to operate by 1349. An annual fair was recorded in 1349-50, and this had lapsed by 1399.
