The Clancy Barracks date from about 1857 and have had a long connection with artillery, cavalry, and ordnance. They have been associated with various military events including the Crimean War, the Boer War, World War 1, and the 1916 rising. The site is now being used for various film and TV show sets, most notably “Ripper Street”.
The only point of entry I could find for this site was over a wall that surrounded a large, modern apartment complex (not ideal!). I always walk around the whole perimeter of a site to check where the safest and most legal way in is before I actually go in. Due to the fact this is an important historical military site and now being used for films, it’s pretty well protected.
