The castle finished by a son after his father's death

Graf Walram IV. von Nassau-Idstein ordered the construction of Burg Wallrabenstein around 1390. The castle served to secure the northeast border of the Nassau territory and the nearby town of Holtzhausen. As construction began, the residents of Holtzhausen settled directly near the castle.

In the same year the work began, Walram's older brother, the Archbishop of Mainz, died. Walram IV. himself died on November 7, 1393, at the age of 40, before the castle was finished. It was his son, Graf Adolf II. von Nassau-Idstein, who finished the construction of the castle in 1393.

Once finished, the castle was pledged by Adolf II. to Henne von Reifenberg. A dispute over the name 'Walrabenstein' eventually required nine arbitrators to settle the matter in 1406 between Adolf II. Graf zu Idstein and Hengin von Reifenberg.

Today, the ruin stands in the district of Wallrabenstein in the municipality of Hünstetten. It remains a physical record of the 14th-century construction and the territorial history of the Nassau-Idstein lands.
