Surviving alongside the Lower Lines and the Great Lines Field of Fire, the Inner Lines survive as an example of the change to civilian recreational use of redudant military installations. Recreational use was formally established in 1868, havoing previously been part of the Great Lines Fortification built in 1755. During the whole period when the military ramparts were operational, and arguably up to the present (2014) the Inner Lines maintained a considerable area of open ground. Originally used for mustering and manoeuvring troops, later uses including allotments and recreational areas for military personel. The C19 recreation ground was laid out around an C18 domestic garden. Virtually all of the designed features of the C18 pleasure grounds, and most of the C19 Garrison Recreation ground, are now gone (2014), buried or degraded. However, due to the position of the Inner Lines, adjacent to the current military housing, the site continues in its original purpose of providing a recreational ground for soldiers and their families.
