To the southeast of the center of Tringenstein lies the site of the former Tringenstein Castle on a mountain cone of the Schelder Forest. Only remnants of the foundation walls and a round arched gate opening in the northern castle district and the striking location, which offers a delightful view of Tringenstein and the surrounding landscape of the Schelder forest, are preserved. The castle was built in 1351 by Adelheid von Nassau, a countermeasure to the foundation of Neu-Dernbach (see district history and "Dernbacher feud"). The castle becomes the seat of the court under the care of several noble families. With the end of the Middle Ages, the castle lost its function as a defense structure, but remained the destination of hunting trips during the Nassau rule and was also the short-term residence of Johann IV and Johann V von Nassau-Dillenburg. From the 16th century, courtyards were built outside the castle, the core of the village of Tringenslein. In the 17th century - during the Thirty Years' War - the castle was a refuge for the surrounding towns; In 1625 Count Ludwig Heinrich moved to Tringenstein after the plague broke out in Dillenburg. The final decline of the castle began in the 18th century: the offices of Tringenstein and Ebersbach were merged, the official seat went to Ebersbach. The castle has been without function since then and the decline began. The only use today is a memorial built on the eastern edge of the castle district. The area with the ruined remains of Tringenstein Castle is a cultural monument due to its historical significance.
