The Roman Colleges, also referred to as the Pontifical Colleges in Rome, are institutions established and maintained in Rome for the education of future ecclesiastics of the Roman Catholic Church. Traditionally many were for students of a particular nationality. The colleges are halls of residence in which the students follow the usual seminary exercises of piety, study in private, and review the subjects treated in class. In some colleges there are special courses of instruction (languages, music, archaeology, etc.) but the regular courses in philosophy and theology are given in a few large central institutions, such as Pontifical Urbaniana University, the Pontifical Gregorian University, the Pontifical Lateran University, and the Pontifical University of Saint Thomas Aquinas, Angelicum.
