BADEN-WÜRTTEMBERG – Festungsruine Hohentwiel

Spread across nine hectares, the largest fortress ruins in Germany offer one of the country’s most impressive vistas: from Hohentwiel, you can see across Lake Constance, over the gentle rolling hills of the Thurgau region to the majestic peaks of the Alps. Hohentwiel is a large rocky outcrop, one of the many bizarre volcanic formations of the Hegau region. The steep crags, which jut out starkly from the surrounding landscape, presented ideal vantage points for fortresses and other structures. The first castle was built on Hohentwiel in 914. Hohentwiel’s imposing ramparts and casemates, its fallen towers and defiant ruins, still evoke the military might of this once-invincible fortress. The surrounding volcanic crags are a now a nature reserve, offering a unique habitat to many rare species of flora and fauna. Today, more than 80,000 visitors a year come to admire this special place.
