Carlisle Castle was listed as (List Entry Number: 1014579) in August 1996, by what is now Historic England. The listing for the Scheduled Ancient Monument status includes "the upstanding and buried remains of Carlisle medieval tower keep castle, two lengths of Carlisle city wall, a 16th century battery, and the buried remains of much of the Roman fort known as Luguvalium, a large part of which underlies the later castle." In 2016, Historic England undertook the first official investigation into the historic graffiti and carvings scattered over the castle site, using photogrammetric techniques to record findings. The ‘Prisoners’ Carvings’ in the Keep, and a medieval door covered in etchings, were laser scanned, photographed and filmed, alongside a Roman altar stone, medieval and postmediaeval graffiti and carvings across the complex, to produce 3D models as a record of their current condition. Museum The Castle houses Cumbria's Museum of Military Life. The museum "relates the history of Cumbria’s County Infantry Regiment, the Border Regiment and the King’s Own Royal Border Regiment and local Militia", according to Visit Cumbria guide.
