Burg Katz is a castle above the German town of St. Goarshausen. It is a truly remarkable structure tucked in the hillside.
It was built around 1371 by Count Wilhelm II of Katzenelnbogen. It was originally used in the military as a commanding station.
The castle also provided a transportation corridor through the German countryside. Burg Katz was an attractive target and was scarred by many battles.
Spaniards conducted a siege in 1626 and the French tried to capture it in 1684 and again in 1692.
In 1801, it was ultimately owned by France and Napoleon decided to blow it up in 1806. It remained in disrepair well into the late 19th century.
