Plymouth Blockhouse, Mount Batten has been described as a probable Artillery Fort.

There are no visible remains.

This site is a scheduled monument protected by law.
This is a Grade 2* listed building protected by law*.


C17 artillery tower, and a Civil War breastwork as well as sundry World War II remains. Grenville's map of the fortifications on Mount Batten in 1586-8 showed a new bulwark and 3 artillery pieces, the latter facing west and south-west, but no surface remains are identifiable. In the C17 an artillery tower of three storeys was built on the headland of Mount Battern perhaps between 1645-60 as part of the defences of Plymouth Sound. It is a circular stone tower 9.1 metres high, 14 metres in diameter, and with walls approximately 1 metre thick; it has a castellated parapet with embrasures for ten guns. A Civil War earthwork was noted close to the tower in 1882; this earthwork is thought to date from the siege of Plymouth from 1643-45 and may be part of a Parliamentarian retreat-work shown on a contemporary Royalist map. It survives as a slight bank and ditch on the south western side of the seaward slope of the headland. During World War II the need for effective air and coastal defence saw the area of Mount Battern given over to both air and sea defence structures. These structures include the remains of two Light Anti-Aircraft gun emplacements and a signal identification panel on the area of the plateau south west of the artillery tower, and two L-shaped anti-submarine searchlight batteries of brick and shuttered concrete construction which survive intact minus their searchlights; they lie just above the high water mark of medium tides on the south west rock bench of the headland.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
