The university has two major campuses, both in Debrecen: the older main, which hosts the majority of the departments of the faculties of humanities, science, medicine, music and also the botanical garden; and the younger "Kassai-road campus" where most of the buildings of the faculties of law economy, and informatics are located. However, besides these, numerous smaller units are spread across the city, for example the departments of physics and the Institute of Nuclear Research of the HAS forming a compact "mini-campus", or the Faculty of Agronomy. The Faculty of Engineering also enjoys its own campus on Ótemető street.[6]
