Corn mill built in 1889 on the by-pass of Swansea Canal Lock 24 or Gurnos Road or Gurnos Mill Lock (20,520m from Swansea Basin). Built to serve the growing population working at Ystalyfera Iron and Tinplateworks. It was disused by 1924. The site of the late nineteenth-century cornmill on its bypass and is now demolished and its foundations presumably remain under the open ground to the north of the former road bridge over the canal. South of the lock the main valley road branches north following the line of a former railway, and the buried canal continues, now used as a cycle path, over the Twrch Aqueduct.
