Mittertor is a magnificent historical gate and the only surviving entrance to the old town of Rosenheim. Built as far back as the 14th century, it served for centuries as the city's eastern outpost and customs point. This architectural treasure, located in the heart of Germany, is a unique blend of defensive strength and elegant Neo-Gothic style.

The building stands out for its characteristic appearance: a powerful stone base with a pointed archway contrasts with the neat upper floors. The snow-white facade is decorated with windows featuring bright shutters, and the structure is crowned by a high tented roof with a small dome, a bell, and the ancient city clock, which still marks the passage of time in the city.
Today, the Rosenheim City Museum is housed within the walls of this gate. Its collection includes about 5,000 unique exhibits covering a vast period of history—from the days of Ancient Roman rule to the mid-20th century. Visitors can see household items, trade artifacts, and handicrafts that tell the story of how the cultural and economic life of this region of Bavaria was formed.
