St Mary's College, Blairs (commonly known as Blairs College), situated near Aberdeen in Scotland, was from 1829 to 1986 a junior seminary for boys and young men studying for the Roman Catholic priesthood. Part of the former college now houses Blairs Museum, the museum of Scotland's Catholic heritage. The New Chapel is a Category A listed building, with the other buildings listed as Category B.
Lying on the south bank of the River Dee, between Kirkton of Maryculter and Aberdeen, the land on which the seminary was built was originally owned by the Knights Hospitallers of St John of Jerusalem, before passing to the Menzies family in 1542. In 1827 the land was donated to the Bishops of the Roman Catholic Church in Scotland, and the original building, Menzies House, converted into a seminary for 25 pupils. In 1829 Lismore Seminary and Aquhorthies College were merged, then closed and the students moved to Blairs College.
As well as the Blairs Museum, the site also hosts the Blairs Library, a collection of 270,000 books concerning Scottish Catholic history. In 2012, it was proposed that the collection be moved to Aberdeen University Library. In 2012, the site was also proposed by Muir Homes to be made into a housing development.
