Alsbach Castle was built around 1235 by Gottfried I von Bickenbach and called Bickenbach Castle. The Bickenbachs were a minor noble family from the Odenwald. This more-substantial structure was probably the successor to an earlier motte and bailey castle located on nearby Weiler Hill and was built to protect the family’s territorial interests after Lorsch Abbey became a subordinate of the Archbishopric of Mainz.
In 1463, the free city of Frankfurt, in retaliation for a robbery committed against one of the communal owners, overran the castle, plundered it and burnt it to the ground. It was quickly rebuilt. During the War of Succession of Landshut the Landgrave of Hessen, Wilhelm I, took the castle in 1504 without a fight, and it remained, thereafter, in Hessen hands.
During the Thirty Years War (1618 - 1648), the castle was used by the local population as a place of refuge, though afterwards it was abandoned, fell into disrepair and was used as a source of building stones for other structures. It was not until the end of the 19th century that the Grand Duke of Hesse-Darmstadt secured the ruins, and after World War II, restoration began in earnest. The castle was then renamed Alsbacher Schloss.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
