The Yorkshire Architectural and York Archaeological Society (Y.A.Y.A.S.) is a learned society formed in 1842 as the Yorkshire Architectural Society. Its membership was made up of clergymen and laymen led by Rev. George Ayliffe Poole from Leeds. Its main objectives were the study of ecclesiastical architecture and design, and the restoration of churches within Yorkshire; it also intended to promote improvements in the design of future ecclesiastical buildings.
