The Oxfordshire Architectural and Historical Society (OAHS) has existed in one form or another since at least 1839, although with its current name only since 1972.
The Society attracts members who are interested in the archaeology, architecture and history of Oxford and Oxfordshire in England.
As well as the annual publication of Oxoniensia, OAHS organises lectures and excursions, which are open to all members.
The OAHS has a reciprocal arrangement with the Oxford University Archaeological Society, which allows the members of one body to attend meetings and excursions organised by the other.
Oxoniensia, started in 1936, is the annual journal of OAHS, which is sent to all members.
