Welcome to the official web site of the Old Caledonia Artificer Apprentices Association.  Within these pages you will find information relevant to our Association and also HMS Caledonia - Rosyth’s College of Knowledge on the Hill - where the majority of our members dedicated their youth to the pursuit of engineering knowledge, alongside other, more leisurely, pastimes (as some of the pages reveal).

We hope that you enjoy your OCAAA browsing experience, but should you be unable to find that which you seek, or experience technical problems with the site, please do not hesitate to drop us an email. You’ll find our address under the “Contact OCAAA” button at the head of each page.
