Festung Hohentwiel

Festung Hohentwiel is an expansive ruin spread across a volcanic mountain near Singen, showing defensive walls, courtyards, and towers across multiple levels. Built on a phonolite peak, the complex contains foundations and structures from different periods of construction and use.

The fortress was first documented in 915 and experienced five sieges during the Thirty Years' War. French forces destroyed it deliberately in 1801 to eliminate its military threat.

The fortress hosts seasonal performances and festivals that draw crowds to its stone structures. These gatherings have transformed the ruins into a living cultural space where music and art blend with history.

The hike to the site starts from Singen via marked trails, with the route taking 30 to 60 minutes depending on your entry point. Sturdy shoes and windproof clothing are important since the path is steep and the hilltop location means exposure to weather.

The ruins rank among Germany's largest and offer views extending to Lake Constance and the Alps on clear days. These far-reaching vistas make the site an overlooked viewing point that many visitors underestimate.
