Some walking time estimates in case you like to stroll:

Walking times to on campus (and slightly off-campus) lunch facilities:

Even though 80% of the downtown was destroyed in multiple air raids by the Allies during World War II, there are many interesting spots to discover in Mainz. City walks are described here.

Among the museums, the Gutenberg Museum honoring the inventor of book printing and presenting his technical and artistic achievements, is certainly special. It will even be nicer, once the museum remodel is complete.

A full list of museums can be found here, in German or in English.

Among the churches, the 1000-year-old Mainz Cathedral and the painted glass windows by Chagall in St. Stephan are recommended. Locals are also very proud of the modern architecture of the new synagogue (credits Wikipedia). 

The old town and the riverfront are always worth a visit. Note that the signs of streets parallel to the Rhine River are blue, while those perpendicular to the river are red.

Mainz is also known for its “political” carnival and political cabaret. There is even a walk of fame.

Some of the sights in Mainz are even unknown to many locals. Examples are the “Haus zum Stein”; the oldest house in town (1250), or the 300-year-old underground tunnel system link. 

If you happen to stay longer, you may want to explore more of the region. The wine country on the “wrong” side of the Rhine always used to be much richer than the Mainz side. The Rheingau is famous for its wines, such as those from Schloß Volrath, cute villages such as Eltville, and monasteries such as Kloster Eberbach (credits Wikipedia).
