Originally, the Tithe Barn housed the tithes paid by the local community to the monks of St Mary's Priory, nearby. Over the centuries, the building has been reinvented many times, serving as a coach house, theatre, timber warehouse, grain store, Women’s Institute shop, carpet warehouse, auction house and disco. The building is now a visitor centre, owned and managed by St. Mary's Priory Church and is open to the public. Access is free.
The current building is probably sixteenth century. It is has random rubble walls with three barn doors on the side facing the church. There are four rows of pigeon holes under the eaves with perching ledges below them. There are three circular windows on the long side and one above the new doors at one end. These may originally have been for loading hay during its time as a coach house.
The barn now houses an exhibition about St. Mary’s Priory and the Abergavenny Tapestry. It also houses a food hall, gift shop and tea room.
