Religions of Aberdeen

St Nicholas was the only burgh kirk and one of Scotland's largest parish churches. Like a number of other Scottish kirks, it was subdivided after the Reformation, in this case into the East and West churches. At this time, the city also was home to houses of the Carmelites (Whitefriars) and Franciscans (Greyfriars), the latter of which surviving in modified form as the chapel of Marischal College as late as the early 20th century.

St Machar's Cathedral was formed twenty years after David I (1124–53) transferred the pre-Reformation Diocese from Mortlach in Banffshire to Old Aberdeen in 1137. With the exception of the episcopate of William Elphinstone (1484–1511), building progressed slowly. Gavin Dunbar, who followed him in 1518, completed the structure by adding the two western spires and the southern transept. It is now a congregation of the Church of Scotland. Aberdeen has two other cathedrals; St. Mary's Cathedral is a Roman Catholic cathedral in Gothic style, erected in 1859. In addition, St. Andrew's Cathedral serves the Scottish Episcopal Church. It was constructed in 1817 as Archibald Simpson's first commission and contains a memorial to the consecration of the first bishop of the Episcopal Church in the United States of America, which took place nearby.

Numerous other Protestant denominations have a presence in Aberdeen. The Salvation Army citadel on the Castlegate dominates the view of east end of Union Street. In addition, there is a Unitarian church, established in 1833 and located in Skene Terrace. Christadelphians have been present in Aberdeen since at least 1844. Over the years, they have rented space to meet at a number of locations and currently meet in the Inchgarth Community Centre in Garthdee. There is also a Quaker meetinghouse on Crown street, the only purpose built Quaker House in Scotland that is still in use
