Stein Castle
The castle ruin Stein, also known as Zullestein, Kellerei Stein, or Schlossbuckel, was a lowland castle with an associated settlement near Nordheim in the Bergstraße district, Hesse, Germany. Its history dates back to Roman times before it became a medieval complex and was completely destroyed in the late 17th century.
History+
As early as the second half of the 3rd century, a late Roman fortress, a burgus, was built at the Weschnitz estuary, serving as a watchtower and landing stage. This complex secured the transport routes for heavy stone blocks, which were transported via the Weschnitz to Roman forts, such as the one in Trier. In the 9th century, King Louis the German gifted estates in the settlement of Zullestein to Count Werner, who later transferred them to Lorsch Abbey. This led to the development of the site as a port and trading post. In 995, Emperor Otto III granted market rights to Stein Castle, giving Lorsch Abbey the rights of use and making the castle the administrative seat of the 'Kellerei' (stewardship). In 1068, Stein passed to the Bishops of Worms, who erected a new castle. From 1232, a round keep was added.
