Tregantle Down Battery
Tregantle Down Battery was built between 1888 and 1894 to mount four 9-inch RML High Angle Fire (HAF) guns.
The Battery had two groups of two guns in a line. The magazines were underground between the two gun groups. The layout of the gun line was similar to Gharghur High Angle Fire Battery in Malta.
The site has now been completely lost.
Other HAF batteries defending Plymouth were Rame Church Battery (two guns) and Hawkins Battery (four guns). Both were built about the same time as Tregantle Down Battery.
