Halifax is a minster town in the Metropolitan Borough of Calderdale in West Yorkshire, England. It is the commercial, cultural and administrative centre of the borough, and the headquarters of Calderdale Council. In the 15th century, the town became an economic hub of the old West Riding of Yorkshire, primarily in woollen manufacture. Halifax is the largest town in the wider Calderdale borough. Halifax was a mill town during the industrial revolution.
From New Year's Day 1779, manufacturers and mercers dealt internationally in such articles through its grandiose square, the Piece Hall. Halifax is known for Mackintosh's chocolate and toffee products including Rolo and Quality Street. The Halifax Bank was founded and has large offices in the town. Dean Clough, north of the town centre, was once one of the largest textile factories in the world at more than 1⁄2 mile long; today the building has been converted for office and retail use including a gym, theatre, Travelodge and radio station.
