Falkenstein Castle is a ruined imperial castle dating to the Middle Ages. It is situated above the eponymous village of Falkenstein on the Donnersberg, the highest point in the Palatinate region, which rises within the German state of Rhineland-Palatinate.
Falkenstein is first recorded in 1135 as the castle of the lords of Falkenstein, a branch of the lords of Bolanden. It is mentioned again in 1233 in the possession of Philip I, the Lord of Falkenstein, the Imperial Chamberlain (Reichskämmerer) and burgvogt at Trifels Castle, where the Imperial Regalia were guarded. After the death of the imperial chamberlain of Münzenberg Philip I took over the office. In 1255 he inherited the Landvogtei in the Wetterau. Lich was later the centre of the territory of Philip I of Falkenstein. In the mid-14th century the Falkensteins built New Falkenstein in the Taunus region of Germany.
Around 1500 Uhland I acquired the castle rights and expanded the castle further. His descendants purchased Schloss Bertholdstein near the town of Fehring in the Styria in Austria and subsequently settled there.
In 1647 Falkenstein was besieged by French troops, stormed and slighted. In 1736, Falkenstein Castle and the County of Falkenstein went to the imperial House of Habsburg. In 1794, it was destroyed once more by the French during the Coalition Wars, since when it has remained a ruin, albeit partially restored after 1979.
Partly preserved are the bergfried, remains of the outer walls of the great hall (Ritterhaus), the shield wall, the enceinte and the cistern.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
