The Leibniz-Zentrum für Archäologie (LEIZA), former Römisch-Germanisches Zentralmuseum (RGZM), is a globally active research institution for archaeology. Founded in 1852 by the Gesamtverein der deutschen Geschichts- und Altertumsvereine, it has been a foundation under public law since 1870.

Research at the LEIZA ranges from the Palaeolithic to the late Middle Ages. A major strength here is the collaboration between science, restoration and archaeometry.

Due to its interdisciplinary and international orientation, the institute has a sustainable network of cooperation partners. A special feature is the cooperation with China, which will focus on cultural-historical evaluation and scientific analysis in the future.

The in-house publishing house publishes three important journals and numerous scientific monographs. Permanent and special exhibitions, popular science publications and various events serve to communicate science.
