Penlee Battery

Penlee Battery is a nature reserve lying on the coastal headland of Penlee Point on the Rame Peninsula, in southeast Cornwall, United Kingdom.

The site was formerly a fort, constructed from about 1890. It contained the largest gun of the Plymouth defences, a 13.5 inch BL, and was in active service through both World Wars. Some gun emplacements still remain.

It is famous among dragonfly enthusiasts as the site where Britain's first Green Darner dragonfly was found, in 1998.
