Philipps-Universität Marburg

uni-marburg.de

Herzlich willkommen an der Philipps-Universität Marburg! Die Philipps-Universität, 1527 gegründet, gehört zu den traditionsreichsten Hochschulen Deutschlands. Die rund 21.000 Studierenden machen mehr als ein Viertel der Marburger Bevölkerung aus, und neben einem naturwissenschaftlichen Campus außerhalb des Zentrums verteilen sich viele Institute und Forschungseinrichtungen über die gesamte Innenstadt. Noch heute gilt deshalb das literarische Bonmot: „Andere Städte haben eine Universität, Marburg ist eine.“
