Description

The defences for Portsmouth were under construction between 1421 and 1424 but by 1539 they were so decayed that new ramparts had to be thrown up. These had fallen down two years later but were rebuilt in the late 16th century. During the Civil War Portsmouth was one of the most important and heavily defended south coast ports. The Royalist garrison was secure behind the medieval earth ramparts and stone walls until Portsmouth surrendered in September 1642. The fortifications were remodelled by Sir Bernard de Gomme between 1665-8 and a map by de Gomme shows that these defences were practically identical with those shown on the OS 25'' of 1867. By 1800 the town had become a military fortress. The town walls were demolished between 1871 and 1878. (PastScape)
Comments

Earth rampart raised on landward side of town in 1386, continued along seafront from 1560 and strengthened elsewhere by arrow head bastions. Now mainly demolished. Kings Bastion surviving part of Portsmouth's defences. Rebuilt to its present stone form in C17. Begun as an earthwork c.1522. Also The Saluting Platform - Battery Platform dated c.1522-1526 and altered in 1568. It was redesigned in the late C16 and early C19. In 1987 part of the wall collapsed during a storm. See also Round and Square Towers which survive and formed part of these defences. Murage granted in 1342 but town petitioned for its repel because of lost trade two years later.

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.
