Building 6: ?charge magazine at Powder Mills gunpowder factory. Located 50-60 metres south of incorporating mill (Building 3) to which it is connected by an embanked track. Slightly larger than the other two magazines (Buildings s 4 and 5). Circa 3 metres wide by 5-6 metres long. The south wall survives to a height of circa 0.5 metres and seems to contain a central doorway. A small hollow running down the centre seems to link up with one coming from the direction of the incorporating mill.

Ruins of gunpowder mill. Established in 1844 by a Plymouth alderman George Frean. Originally quite an extensive complex of buildings running up the valley with several water wheels turned by water from a leat and with two chimneys. All the buildings are now in varying degrees of ruin although one chimney survives and three main groups are recognisable of granite rubble with granite lintels, all roofless. The chimney is well constructed with stringcourse near the top and plinth. It has a covered channel running downhill from it towards the largest ruinous building. The invention of dynamite in 1867 rapidly superceded gunpowder. and the mills, which employed about 100 men closed in the 1890s.

The gunpowder factory at Powder Mills survives well and contains a complete range of buildings and other structures and features associated with the industry. Many of the buildings remain essentially intact, with only the roofs and machinery having been removed. The system of leats and trackways provides useful additional information concerning the character of the factory. The unique survival of the associated proving mortar emphasises the quality of the surviving archaeology. Together with a comprehensive historical background this represents a fine example of a gunpowder production site.
