The Piece Hall is a Grade I listed building in Halifax, West Yorkshire, England. It was built as a cloth hall for handloom weavers to sell the woollen cloth "pieces" they had produced. It opened on 1 January 1779, with 315 separate rooms arranged around a central open courtyard. As factories started up in the early nineteenth century the trade in handwoven wool declined and around 1815 the rules were changed to allow the sale of cotton goods. As of 2016 the Piece Hall is closed while redevelopment takes place. The work is due to be completed in 2017.
