Towneley Altarpiece - although recorded as part of the furniture collection, it is valued separately from the rest of that collection. It was made in Antwerp around 1525 and is of national importance.
Whalley Abbey vestments - although recorded as part of the textile collection, these two vestments are valued separately from the rest of that collection. They were made around 1425 and are of national importance.
Local crafts, industrial and social history - with an accession register distinct from that of the main museum collections.
