Archibald Simpson (4 May 1790 – 23 March 1847) was a Scottish architect, who along with his rival John Smith, is regarded as having fashioned the character of Aberdeen as "The Granite City". Dubbed the Architect of Aberdeen, Archibald Simpson designed several important buildings in his native city.
His masterpiece is the former bank, now a Public House bearing his name on Union Street.
Archibald Simpson also designed Marischal College (University of Aberdeen) and St Andrews Cathedral, both just a short walk away.
A stone memorial was erected to the famous Architect here in Bon Accord Square in 1975
