Rhyddings Mill, Rhyddings Street, 1856, Grade II – 183911. Former cotton weaving mill. Coursed rubble, much of it rusticated, with Welsh slate roofs. The listed items consist of the principal warehouse and preparation block with weaving shed to rear, the works entrance and engine house adjacent to left, the chimney stack, and the front perimeter walls and two entrance lodges. Internally only the principal range and weaving sheds are of special interest: the warehouse was not fireproof, with timber floors and chamfered beams supported by iron cradles on piers of circular section with rudimentary moulded
capitals; similar columns to weaving sheds. Rhyddings Mill is an interesting example of a mid-19th century textile mill designed with considerable architectural pretensions as part of a larger-scale urban development consisting of employees' housing, speculative housing and the parish church. This was the first independent weaving mill in Oswaldtwistle, built by Watson Brothers, later Robert Watson & Sons, who also had a mill at Stonebridge, on the other side of the river. In 1930, the mill had 280 employees and 699 looms worked by a 270 hp beam engine; manufactured fabrics were mainly printers, dhooties, acconettes and dobby cloth. A second weaving shed was erected in 1951 and equipped with 250 electrically driven looms. Production ceased on the site in 1957.

So it looks like the chimney stack grade 2 listed.
