Site visited on 6th June 1950. Clapper bridge in very good condition with two clappers and two arches. All the work is dry-stone with earth covering over the clappers. Width of bridge 3.0 metres by 4.5 metres long. The stonework exhibits drillmarks, suggesting a post-1800 date.

Clapper bridge over Cherry Brook. Early-mid 19th century. Rough granite blocks to pier and jambs, and granite slab lintels. The bridge is of two spans. Drill-holes in a number of the stones suggest that the bridge was constructed after the turn of the 19th century (when this method of splitting granite was introduced) and it may date from circa 1844 when the nearby Powder Mills were built. This form of bridge construction on Dartmoor was first used probably in Early Medieval times but later examples such as this one also occur.


English Heritage, 9/10/1981, Gunpowder factory at Powder Mills (Schedule Document). SDV350194.

The gunpowder factory at Powder Mills survives well and contains a complete range of buildings and other structures and features associated with the industry.
The monument, which falls into five areas, includes a gunpowder factory, a partially enclosed stone hut circle settlement and a round cairn situated adjacent to the Cherry Brook. The gunpowder factory, which is Listed Grade II, comprises at least 18 buildings involved in the production, storage and management of gunpowder. Many of these buildings contained machinery which was powered by water which was carried to the site by three large leats from the East Dart and Cherry Brook rivers. These are included in the scheduling. A system of trackways link the buildings and the river was crossed by way of clapper bridges. Modern post and wire fences, a shed and piles of sand and other materials associated with a consolidation programme are excluded from the scheduling, although the ground beneath them is included.
