The Original History of the castle Hayn
The castle Hayn was built as a seat of the imperial stewards who were entrusted with the administration of the big wild spell Dreieich ( according to the wild spell of the Main shore handed out so-called Dreieicher Weisthum of emperors Ludwig of Bavaria of 1338 about Darmstadt and from the right Main shore along the Nidda to Aschaffenburg).
The emperor himself visited the castle only if he was in the wide woods on hunt.
The first one mentioned in a document steward and developer of the originally tower castle was Eberhard von Hagen. Only with takeover of its office the family assumed the name Hagen (Hagen means in old high German in possibly surrounded court). About 1080 he built the 5-stored residential tower on a small island in the Hengstbachtal. He was surrounded by high curtain walls and a wide water jump.

A town wall with embankment and ditch surrounded the originating castle man's town.
The Romanesque town gate - the later middle gate, today not more existing - was the only access to castle and town. After the extinction of von Hagen-Münzberg in 1255 the castle fell in a distribution of estates to several men. Till 1286 von Falkenstein 5/6 of the castle could take over, 1/6 remained with gens of Hanau. The castle was further upgraded in the future. The palace and the church were enlarged, other smaller dwelling houses within the castle walls followed.
A mighty gate tower stored the access to the castle. In 1256 citizens (cives) are mentioned for the first time in a place called Hagen ( Hayn ), town rights existed, nevertheless, absolutely already some years longer. In 1350 the town was extended around a craftsman's settlement, the suburb ( the so-called waiter grove), and received up to the town gate resulted a new the magnitude visible even today of the Old Town.
