Following the removal of the external render from the Moot Hall, Appleby-in-Westmorland, Cumbria, during a programme of renovation, Greenlane Archaeology was commissioned to record a range of features of interest that had been revealed. This followed on from an extensive investigation into the history of the building and dendrochronological investigation carried out in 2018. The building recording was carried out to Historic England Level 2/3 type standards. The Moot Hall is considered to have been built at the end of the 16th century, possibly in 1596, as per a datestone in the south-east elevation, which is partially confirmed by the recent dendrochronological dating. The documentary sources mention some new building in the early 17th century, regular repairs, and a new extension to the north-west is recorded in 1800. By this time the lower level was being used for shops. A single reference to a 'blackhole' in 1847 suggests that part of it might have been used as a jail. The building recording revealed a number of features of interest, including blocked mullion windows in the south-east and south-west elevations, evidence that many of the tall regular windows were inserted, a former gable in the south-east elevation, a row of former doorways (now windows) in the south-west, and a blocked doorway and row of small high-level windows at the north-west end of the south-west elevation. It is likely that the original gable represents the form of the late 16th century building, which was raised to its current height in the early 17th century. The north-western extension seems earlier than the suggested date of 1800; it is shown on a plan of Appleby dated 1754, with a doorway depicted matching the blocked one revealed, and the form of the v-jointed quoins at this end also fits for an 18th century date. It is suggested that the row of small high-level windows correspond to a former jail, the 'blackhole' recorded in 1847, and that part of the north-west end was used for this prior to the construction of the Shire Hall and new jail in Appleby in the 1770s. The evidence for a jail or lockup is particularly significant.
