Turmburg Eschborn, Medieval castle in Eschborn, Germany.

Turmburg Eschborn is a castle built on an artificial hill in northern Eschborn, featuring a square defensive tower as its main structure. The fortress was constructed with thick stone walls that formed the core of this fortified settlement used for both protection and administration.

The castle was built in the 11th century, linked to the Lords of Eschborn who appear in records from the late 12th to early 13th century before moving their seat to Kronberg. It was first documented in 1339 in a property register of Knight Rudolf von Sachsenhausen. In 1622, during the Battle of Höchst in the Thirty Years' War, the complex and almost the entire town were destroyed.

The street names Burgstraße, Am Hofgraben and Am Burggraben mark the footprint of the vanished castle. The site is linked to the Lords of Eschborn, who appear in records from the late 12th to early 13th century and soon moved their seat to Kronberg. Eschborn remained a fief of the Lords of Cronberg until that line died out in 1704 and their rule passed to Kurmainz.

Nothing of the castle is visible today: the site is overbuilt, and the streets Burgstraße, Am Hofgraben and Am Burggraben trace its former extent. Walk these three streets to follow the perimeter; the excavated finds, including an anvil, axes and a stone jug, went to the 1899 publication rather than to a display on site.

Archaeological digs uncovered evidence of craft activities from the medieval period, showing that daily production and trade occupied people here alongside military functions. These findings reveal a more complex picture of how the fortress site actually functioned in everyday medieval life.
