Schloss Laubach is first mentioned in a list of properties of the Hersfeld monastery in 786 C.E.

In 1255 the estate was granted to the Lords of Hanau, and later it was owned by the Counts of Falkenstein.

In 1475 Kuno, Count of Solms-Laubach was granted permission by Frederick III, Holy Roman Emperor to add fortifications to the castle and the surrounding town.

[2] The architect Licher Baum Wolff Werner rebuilt the castle towers in 1533.

Three of the four original fortified round towers still stand, and baroque hoods were later added onto them.
