Barn Approximately 10 Metres North East of the Hall

Barn approximately 10 metres north-east of The Hall

This building, now a barn, was originally a grange hall built in the late 12th century, probably for Guisborough Priory. It was converted to a chapel before 1430 and has undergone numerous alterations since. The structure is constructed of Corallian limestone with a slate roof.

The west front presents two storeys with two windows and two doorways to the left. The end opening features a double-chamfered 2-centred, roll-moulded arch over a board door and screen with a square-paned pointed overlight. To the right is a lower plank door in a chamfered opening with rough quoins and 2-centred arch. Above this door and further right are two blocked 3-light windows with cusped pointed heads in elliptical-arched, double-chamfered openings.

The east front also displays two storeys with irregular openings. An inserted doorway with timber lintel sits to the right of centre. At the centre left is an earlier blocked doorway with a 2-centred head. Further left is a deeply-splayed chamfered opening with a segmental head containing a recessed trefoil-headed light. To the right of the blocked doorway at first-floor level is an original window, partly decayed, of two pointed lights with colonnettes beneath a shallow pointed outer arch on colonnettes showing traces of waterleaf capitals. Further right is another partly blocked elliptical-arched 3-light window similar to those on the west front.

The gable wall to the south has later openings on the ground floor. Above is a 5-light window in a double-chamfered opening, almost completely blocked.

The interior is divided into three unequal parts by two massive beams: one chamfered and the other finely-moulded. Both beams have mortices on their lower side for partitions that were in place in the early 20th century. A 4-centred arch spans the south window above a moulded beam carved with floral motifs. The roof comprises six trusses with chamfered tie beams, wind-braced purlins, and sprocketed rafters.

Following the Norman Conquest, after 1168, Ralphe de Clere granted the Church at Sinnington to the Benedictine nuns at Yedingham, together with lands, and a grange site to Guisborough Priory. In 1239 the Yedingham nuns agreed to support the chapel and buildings owned by Guisborough Priory for entertaining the Canons. The grange was let to Simon of Guisborough in 1368. In 1431–32, Matilda of York, whose second husband was John, Lord Latimer, paid for the installation of partitions and flooring in the "Chapel at Sinnington" and for other works including filling holes and "old windows under the space of the said room". The windows were refenestrated and a floor inserted around 1430. The roof was probably replaced in the 17th century or later. After the Dissolution, the grange probably passed to William Thwaytes as part of the Rectory. The building was in dilapidated condition at the time of resurvey. It is designated as Scheduled Ancient Monument No 146.
