The exhibition traces individual structures and phenomena from the Middle Ages to the early 18th century in Maribor and its surroundings (trade, defence, religion, plague, fires, city government, crafts). The stories are explained by objects, scale models, a replica of a knight's armour that visitors can try on, there is a reconstruction of an alpine smoke house and a medieval tavern. The exhibition is on the ground floor of the renaissance fortification, the city's defence tower from the mid-16th century, built under the direction of the architect Domenico dell'Allia. It shows the anti-Turkish defensive fortifications in Styria and Slavonia under the direction of the architect. Older weapons from the museum's collection are also on display there.
