John Mylne, surveyor and mason, was born in Scotland in 1611, and was a prominent architect by the time he was aged 25. Indeed, in 1636 Mylne was appointed Master Mason to the [Scottish] Crown. This led to a number of opportunities to build key buildings in Edinburgh and Scotland which included churches, abbeys, public buildings and country houses. Mylne did also take commissions south of the border and these included Bretton Hall and Nostell Priory, both in Yorkshire. He was succeeded as Master Mason by his nephew Robert Mylne (1633-1710).
