Visitors can see two banks of kilns dating from the 19th century.

The easiest to see are those built in the 1850s and which are located just across from the car park. The earlier kilns were constructed around the 1840s. These are most visible when the trees aren’t in leaf. A short walk up the track from the car park and looking across the stream. In 2019 a detailed survey was undertaken by the Clwyd-Powys Archaeological Trust of the 1840s kilns and ancillary buildings. This has shown the deterioration in the condition of the structures with collapsed and displace masonry. The survey made use of an 1884 quarry plan, which identifies a smithy, stables, carpenters’ shop and an engine house. If you look carefully you can see significant remains of a two-storey building. This has been identified as a stables. The 1st floor may have been a hayloft. The clue is the remains of a hoist above a first-floor loading door in the gable wall.
