Maison Tavel has several floors as well as an underground full of various exhibits, artifacts and historical objects focusing on Geneva's city history, mostly during medieval times.
Don't miss the beautiful multimedia screening to screen and 3D map of a short movie about the history of Geneva from its early days into modern times called "Geneva, history made-to-measure". Screening audio is available in English, French and German language.
The highlight of the museum is the top floor, hosting the huge 3D map of Geneva town from 1850, when Geneva was smaller and still had fortifications.
