Yorkshire Architectural & York Archaeological Soc.

Founded in 1842, the Yorkshire Architectural and York Archaeological Society (YAYAS) is a registered charity existing to promote the study of the historic heritage of the city of York as well as the county of Yorkshire. The Society seeks to stimulate interest by arranging lectures and excursions, and by issuing publications. It owns the Evelyn Collection of historic lantern slides and negatives of historic York, and has been instrumental in preserving many of the city's unique features.

The Society also produces the journal publication 'York Historian', a copy of which is provided free for members, and is available to purchase through the website. 'York Historian' offers in-depth journal articles often fully illustrated with colour plates on subjects relevant to the history, archaeology and architecture of York and Yorkshire.
