York Historic Environment Record

This area, and part of what later became Deangate was the minster Deanery. It had been the residence of the deans from the 11th century as far as can be ascertained once archbishop Thomas had established the collegiate foundation of a dean and chapter in place of the Anglo-Saxon establishment.
The construction of a new deanery in Dean's Park north of the minster in the late 1820s sealed the fate of the old building, and demolition apparently began in 1830 with the taking down of part of the back of the building.
This can now be seen as part of a wider policy of demolition that began with the Chapter obtaining private acts of parliament in 1814 and 1825 to compulsorily purchase various buildings within the minster close and demolish them to open up vistas of the cathedral. Eventually houses were demolished to create what is now College Green and Duncombe Place.

The old deanery stood relatively close to the cathedral and had a secondary building,
the former prebendal residence of Warthill, attached to its east side which had apparently been annexed to it at some time. It seems that there is no known detailed plan of the building but several basic outlines show its ground footprint overall.
