Onllwyn Ironworks had two blast furnaces, calcining kilns, a smithy and an ironworks shop. Production ended before 1878. The site was eventually cleared.[1]

The isolated works were served by the River Dulais and by an extensive system of tramroads. A tramroad also served the small community nearby (two rows of cottages). In addition to pig iron, iron castings were produced using patterns made on site[2]. This source, and the Coflein entry, include a paln showing the tramroads, houses,quarries, etc.

Did the business become the Dylais Iron and Coal Co? See below.
