The Sorbonne is a building in the Latin Quarter of Paris which from 1253 onwards housed the College of Sorbonne, part of one of the first universities in the world, later renamed University of Paris and commonly known as "the Sorbonne". Today, it continues to house the successor universities of the University of Paris, such as Panthéon-Sorbonne University, Sorbonne University, Sorbonne Nouvelle University and University of Paris, as well as the Chancellerie des Universités de Paris. Sorbonne Université is also now the university resulting from the merger on 1 January 2018 of Paris 6 UPMC and Paris 4 Sorbonne.
