There are no functioning Collegiate churches in Scotland today. It is thought that the first Collegium of canons with its own chapel was formed in St. Andrews in the 13th century, and it is thought that by the Reformation there were more than 50 secular religious houses. The proscription of the Catholic faith in 1567 meant that these houses had to close.Although Scotland endured the Iconoclasm of the Reformation, there are still some handsome structures extant. Some Collegiate churches were converted into local parish Kirks, whilst others have fallen to ruin, some a mixture of the two.
