Foundation and First Mentions
Although the strategically important location at the confluence of rivers attracted settlers as early as the Roman Empire (the military post Pons Aeni was located here), the history of Rosenheim itself begins in the Middle Ages. The city's name is first mentioned in documents in 1234. The settlement received its name from Rosenheim Castle, erected by the Count of Wasserburg on a hill above the Inn River to control the crossing and trade routes.
Key Factors of Development
The transformation of a small settlement into a thriving city was driven by several important circumstances:
- Geography: Its location where the Mangfall River flows into the Inn River made the city a natural transport hub for Bavaria.
- Salt Trade: Rosenheim became a crucial transshipment point for transporting "white gold" from the salt mines of Reichenhall and Berchtesgaden.
- Political Status: Receiving market rights (Marktrecht) in 1328 allowed the city to officially hold fairs and collect tolls, which strengthened its economic independence.
Early Cultural and Economic Features
The economy of early Rosenheim relied on river shipping. Local shipbuilders and carriers formed an influential layer of society. The wealth accumulated through the trade of grain, livestock, and salt was reflected in the city's architectural appearance. It was during this period that the unique style of the central square, Max-Josefs-Platz, was formed, featuring houses in the Inn-Salzach style. These buildings are distinguished by high facades that conceal the roofs, serving as protection against fires and a sign of prosperity.
