The chapel was built at a cost of nearly £308 in 1822–23 (). It was paid for by
Samuel Greg, the founder and owner of
Quarry Bank Mill, and was for the use of his workers. Greg was a
Unitarian but many of his workers were
Baptists. The chapel originally served the latter denomination, but since 1833 it has been Unitarian. A chancel, a porch,
buttresses, and a
plinth were added, the door was moved, the flat roof was replaced by a pitched roof,
Gothic-style windows containing stained glass were inserted, and a larger
bellcote was built. The improvements cost £1,000. Robert Hyde Greg died in 1878, and in the following year a trust was set up to administer the chapel. In 1906 a council room and a
vestry were added, which were designed by
Thomas Worthington. The chapel continued to be administrated by the trust, but by 1977 the Styal estate, other than the chapel, was owned by the
National Trust. The chapel was in need of repairs that could not be afforded by the chapel trust, and its ownership passed to the National Trust. The chapel continues in use as an active Unitarian chapel. ==Architecture==
