Industrial Archaeology of Dartmoor - Quarrying

Quarrying

Dartmoor granite has been used in many Devon and Cornish buildings. The prison at Princetown was built from granite taken from Walkhampton Common. When the horse tramroad from Plymouth to Princetown was completed in 1823, large quantities of granite were more easily transported.

There were three major granite quarries on the moor: Haytor, Foggintor and Merrivale. The granite quarries around Haytor were the source of the stone used in several famous structures, including the New London Bridge, completed in 1831. This granite was transported from the moor via the Haytor Granite Tramway, stretches of which are still visible.

The extensive quarries at Foggintor provided granite for the construction of London's Nelson's Column in the early 1840s, and New Scotland Yard was faced with granite from the quarry at Merrivale. Merrivale Quarry continued excavating and working its own granite until the 1970s, producing gravestones and agricultural rollers. Work at Merrivale continued until the 1990s, for the last 20 years imported stone such as gabbro from Norway and Italian marble was dressed and polished. The unusual pink granite at Great Trowlesworthy Tor was also quarried, and there were many other small granite quarries dotted around the moor. Various metamorphic rocks were also quarried in the metamorphic aureole around the edge of the moor, most notably at Meldon.
