The Scottish Catholic Archives preserves, selects and makes available the archives of the Catholic Church in Scotland and abroad. Responsible for over 800 years of documentary evidence of the Catholic Church in Scotland and the wider world, the Scottish Catholic Archives is a major resource for understanding Scottish and European history.

From letters of Mary, Queen of Scots; baptismal records for individuals such as Arthur Conan Doyle; and papers relating to Oscar Wilde, the collections relate to five continents and are written in at least 12 languages.
