More information : (SZ 6335 9910) King's Bastion (NAT) (1)
King's Bastion, formerly the Green Bulwark, probably dates from 1522 at the earliest phase of the murification of Portsmouth, and was constructed of earth, as was the rest of the town wall at that time. The first masonry bulwark appears to have been built between 1541 and 1545. Modifications continued until 1589, by when it had been converted into a flanker angled bastion. (2)
Although much altered, King's Bastion's present form is due to the modification of the whole defensive system by de Gomme in the late C17th. (3)
