Castle hill
Inscription
On this mountain nose, the Franks built a fortress around 520, at the latest by 720, during their battles against the neighboring Saxons, and to secure the wine route leading from Frankfurt to Frankenberg and later to Paderborn, called Frankenburg, which lost its importance after the end of the Saxon wars (804).
In 1122, the castle hill came into the possession of the Landgraves of Thuringia, who around 1234, in the struggle for power and territorial claims against the Archbishopric of Mainz, built a new castle on this Frankenberg and at the same time founded the city of Frankenberg.
Already in 1376, the citizens of Frankenberg rebelled against the encroachments of their castle lords and burned down the castle. It was not rebuilt. In 1798, Colonel von Todenwarth had the castle ruins demolished, the site levelled, and the trees planted, some of which still exist today. Remnants of the castle walls can still be seen on the south side.
In 1899, a water storage tank was built at the highest point of the city during the construction of the city’s new water supply system.
