Congregationalists had held regular meetings in Halifax since at least 1763 and the Square Chapel was opened in 1772. Square Church, with its 235 ft (71.5 m) tower and spire was opened in 1857 and funded by the Crossley brothers, John and Sir Francis, of Dean Clough.
The Sunday School is now [2003] in use as an arts and performance centre, and is also a Grade II* Listed Building:
SE0925 : Dean Clough, "D Mill" Dean Clough is indeed a wondrous complex. The best view of all is from the North Bridge Flyover. This is barred to pedestrians so don't blame me if your master shot gets you arrested. A half way decent walk round this complex to get pictures is a couple of hours and probably a couple of miles too.
