Schloss Michelbach, Castle in Alzenau, Germany.

Schloss Michelbach is a two-storey baroque building with a mansard roof, seven window axes and two octagonal stair towers flanking the front. A free staircase leads to a plain entrance portal, and a single-storey L-shaped wing extends to the north-east. The core dates from the 16th century and was remodelled around 1700; only the foundations of the earlier water castle remain.

A medieval water castle existed here by the 16th century; a 1592 drawing by Adam Jordan shows it. Baron Ferdinand Kaspar Joseph von Wrede rebuilt it in its present Baroque form around 1700. The Domer family bought it in 1862, and the community of Michelbach acquired it in 1930. After 1949 it served the parish, and from 1980 the local history society set up a collection on the ground floor.

The museum inside, opened after the 2002–2006 renovation, presents the exhibition "Regionalität und Wandel – Streifzüge durch eine Grenzregion" on the region's borders between Mainz, Hanau and Rieneck. In the garden over 100 roses of about 55 varieties grow, and the Museums-Café occupies the Remise. The upper floor holds a hall used for chamber music, cabaret and exhibitions.

The museum in the castle is open to visitors; it can also be booked for events. The baroque garden with over 100 roses in about 55 varieties and the museum café in the remise are worth a visit. The castle is at the intersection of State Roads 2305/2444, north of the Weibersbach stream.

The castle preserves in its stonework the history of two different uses: it first served as a defense structure and later as a residential home for nobility. This shift can be read in the different building styles layered one upon another.
