Ancient quarries, now a National nature reserve.

"The Much Wenlock Limestone Formation has been worked from Wren's Nest, Castle Hill, Hurst Hill and numerous other sites within the borough for many centuries. The keep of Dudley Castle, reputedly constructed in 1300 AD, is built of local limestone. The earliest precise reference to underground workings at Wren's Nest is dated 1796, but there is no doubt that rock was being extracted before this date."
