The last evidence of the medieval fortification is the Upper Tower, built in 1541, also known as the Bread House Tower because bread was once sold in the vault below the tower. Bakers used to have to sell their products at a central location in the town at set prices. This was done in the vault of the town hall until the town fire of 1851 and then for a few years in the Upper Tower. Local history researchers at the end of the 19th century therefore called it the "Bread House Tower". The neighbouring Zieglerwirtshaus shows the features of Inn-Salzach architecture that were also typical of Traunstein until 1851: arcades, bay windows and raised fire walls.
"Town and country, hand in hand, a Gau's hometown": This inscription on the west side of the tower clearly indicates the hometown house housed in both buildings, which houses a town and toy museum. It displays exhibits on bourgeois culture, sacred art and the history of the saltworks; An impressively detailed model depicts the old Traunstein in 1890. The museum also presents historical toys from 1870 to 1960.
