Schloss Günzach, Historical castle in Günzach, Germany.

Schloss Günzach is a three-wing manor house in Günzach, Bavaria, built in 1730 and with its facades updated around 1900. The main building has hipped roofs and is flanked by a machine house to the north and a two-wing farm building to the southeast.

After the secularization of 1803, Johann Friedrich acquired the property and converted it into a brewery. The Gabler family then ran the operation from 1855 to 1875.

The name Günzach comes from the Günz river, on whose banks the manor was built in the "Thal an der Günz". The estate's Catholic chapel, dedicated to the Holy Family, was added in 1902, the same year as the machine house. Eleonore Gabler (1923–2020), the last owner of the estate, sat on the Günzach municipal council from 1972 to 1984.

The complex lies in the Günzach municipality of the Ostallgäu district, in the Thal an der Günz area. The three wings enclose a courtyard, with the machine house on the north side and the two-wing farm building to the southeast. The Catholic chapel of the Holy Family, built in 1902, stands on the grounds.

The 1930 closure of the Gabler family's Schlossbrauerei did not end industrial use: a cotton spinning mill was set up in the buildings, and only later did the first Allgäuer Glasmanufaktur follow. The sequence runs from brewery to spinning mill to glassworks.
