[1][2] The second set of six kilns (Grade II listed) are 250 metres to the east of the main group, following a bend of the park's access road.
[5] Limekilns were originally built for the Black Rock limestone quarries circa 1800, but in 1811 the marshland was reclaimed behind Tenby's burrows and the lime industry lost its easy supply of water.
The second (current) set of twelve kilns were built circa 1865, accessed by a branch of the Pembroke and Tenby Railway (which had been recently opened).
[6] The later kilns are believed to be connected to Saundersfoot colliery blacksmith, John Nash, a substantial property holder in the area at the time.
[1] The Black Rock quarry was still active till the early 1950s, and the Kiln Park caravan and camping park was developed after World War II, marking the end of industrial activity in the area.
