Erbprinzenpalace (Wiesbaden)

Between 1813 and 1817, the Erbprinzenpalais was constructed under the direction of city architect Christian Zais. It was envisioned as a residence for Wilhelm, the hereditary prince of the Dukes of Nassau. As Duke Friedrich August of Nassau-Usingen had no male heirs, the ducal title was to pass to the Nassau-Weilburg line. Friedrich Wilhelm of Nassau-Weilburg, a cousin of the Duke, commissioned the palace for his son Wilhelm. However, fate took a different turn: both Duke Friedrich August and Friedrich Wilhelm died in quick succession in 1816. Wilhelm subsequently became Duke at the age of 23 and moved not into the still unfinished palace, but into Biebrich Palace. The building was subsequently used as an administrative building.
