The TAS Archives is a diverse collection of written, photographic, filmed, digital, textile, and manufactured items that convey the history of The Armidale School and those who have been part of its community, from its earliest manifestations to the present day. 

From crested fine bone china to letters from royalty, valuable firearms and theatrical costumes, it conveys much about who we have been and who we are. A selection of the archives is on display in cabinets in the Lower Maxwell Room, originally built as a library.
The adjacent Sandilands Studio – named in honour of three brothers who gave their lives during the Second World War – is a memorial to the rich history of military service to the country by Old Boys of The Armidale School. Other items of historic interest are also on display in other locations at the school.
