Chirk Mill is a large three storey and attic building, constructed of brick with a slate roof. It is four bays wide and is extended to the south by a further bay. There are timber casement windows throughout and cross windows to the gable ends. To the west is the central entrance and a bracketed cantilevered hoist bay.
There was a mill on the present site in 1506, although the present building dates in part from 1780. Chirk Mill was fitted with a turbine in 1924 and generated power for the town up to 1930. The mill continued working until 1960, after which it diversified into the milling of whiting and later glue. The mill house, which was attached to the east side, was demolished in 1950.
