Barn and attached store in the farmyard at Lyng Court

The barn and attached store form part of the farmyard at Lyng Court. The barn dates to the late medieval period, with significant alterations in the 18th and 19th centuries and an extension around the 19th century. It was originally a tithe barn for Athelney Abbey. Constructed of limestone rubble, some of which is coursed and squared, with a Ham Hill stone plinth and stone and brick dressings, the barn has a hipped pantiled roof.

The barn's plan is rectangular and seven bays, featuring a central threshing bay with opposing entrances. It has been extended to the south. The exterior showcases substantial two-stage buttresses at three corners, with set-offs and remnants of the base of a fourth, north-west buttress. Stone-framed ventilation slits are present on all sides, featuring wide internal splays, some of which are blocked. The principal elevation includes a projecting entrance porch with angle-buttresses and a bricked-up principal opening featuring chamfered jambs and arch springers. A smaller 19th-century doorway has been inserted, along with a blocked four-centred head door opening in the porch’s side wall. Attached to the south is a similar 19th-century covered store constructed of the same materials, with a double Roman tiled roof, half-hipped to the south. The store has a large opening to the east and a smaller entrance with brick dressings on the west side.

Internally, the barn has a later roof structure. In the south half, there are three machine-cut king post trusses with diagonal braces, while the north half features three trusses with principals linked by tie-beams and collars, likely dating to the 19th century. A single, medieval truss with an arch-braced collar survives within the west porch. Projecting corbels set high up probably indicate the position of a former floor level. The central threshing bay has been planked and a modern vehicle inspection pit has been cut into it.

The manor of Lyng was part of King Alfred's endowment to the Benedictine abbey of Athelney in the 10th century. A house known as the "Court" is documented at Lyng in 1529, with a suggestion that there was also a chapel at the site. After the abbey's dissolution in 1539, Lyng passed into lay ownership.

The barn is a substantially intact late medieval tithe barn with an attached 19th-century store. As part of the estate of Athelney Abbey, it retains much of its original plan, outward form, and architectural detailing, despite the loss of its original roof.
