Dean Clough in Halifax, Calderdale, West Yorkshire, England, is a group of large factory buildings built in the 1840s–60s for Crossley's Carpets, becoming one of the world's largest carpet factories (half a mile long with 1,250,000 square feet (116,000 m2) of floorspace). After years of declining production it closed in 1983, when it was bought by a consortium led by Sir Ernest Hall which developed the Grade II listed site for various commercial and cultural uses. It is now seen as a leading example of successful urban regeneration. Dean Clough is located on the north side of Halifax near the Victorian North Bridge and the modern flyover sections of the Burdock Way relief road system. The converted mills now house about 150 large and small businesses and arts venues including Crossley Gall
