Collegium Maius, Medieval university building in Erfurt, Germany

Collegium Maius is a university building with Gothic architecture and a decorative portal on Michaelisstraße in central Erfurt. The late Gothic windows and overall structure provide insight into the importance of this institution during the medieval period.

The building was constructed in 1435 near Michaeliskirche and served as the hub of the university until its destruction in World War II. The postwar reconstruction involved choices between restoring the original or reimagining the site.

The name "Collegium Maius" (Latin for "larger college") distinguished the university's main house from the smaller bursae, such as the Collegium Porta Coeli and the Collegium Marianum. The building also bore the name Collegium Anselminum after Archbishop Anselm Franz von Ingelheim. The late Gothic portal with its ogee arch remains the element to look for on Michaelisstraße.

The building now houses offices of the Evangelical Church in Central Germany, with guided tours available to visitors. Its central location on Michaelisstraße makes it easy to find and part of a larger walk through the old town.

The building was destroyed on 9 February 1945 in Allied bombing raids; only the portal survived, and it was partly reconstructed in 1983. Other architectural fragments were preserved elsewhere. The present building, erected from 1998 in the old style, is a new structure, not a reconstruction of 2011.
