The oldest mention of Mulibah can be found in a Brixen tradition note from around 1050. However, the German name of the place, compared to the pre-German names of Spinges, Vals, Meransen and Rodanc-Rodeneck, suggests that this Bavarian-Rodeneck A young German settlement was planted in the municipal area of one of these places or the mill district of one of these places was formed. Since the main town of Mühlbach, as well as the districts of Spinges, Vals and Meransen, belonged to the parish of Rodeneck for centuries (until 1891), it can be assumed that Rodank-Rodeneck was the original mother community of Mühlbach. The patron saint is Helena, who is celebrated with a traditional procession on the first Sunday after August 18th.
The Mühlbacher Klause is located a little northeast of the main town in the direction of Pustertal. The former valley and road block, which was used to collect customs duties, was mentioned for the first time on January 12, 1269. The hexagonal top part of a payment table (payment stone) made of granite stone and with a coat of arms from 1477 has been preserved. This was privately owned until 1920 and then became the property of the market town of Mühlbach. They handed the payment table over to the “Mühlbacher Klause” association (founded in 1997),[1] which set it up in the renovated Mühlbacher Klause in 2005.
In 1929 Mühlbach was expanded to include the previously independent communities of Meransen, Spinges and Vals. Rodeneck, which was also incorporated in the same year, was made an independent municipality again in 1956.
