Ruine Thürndl, Medieval castle ruins in Hallein, Austria
Ruine Thürndl is a medieval castle in Hallein with a well-preserved tower as its main remaining structure. The northern and eastern walls still stand at around 15 meters high, while the tower footprint measures roughly 9 by 10 meters.
The castle dates to the 13th century and formed part of Hallein's defensive network, specifically protecting the northern gateway of the city. It was one of several fortifications built to safeguard the growing settlement and its trade interests.
The ruins watched over the salt mining areas and trade routes that made the region wealthy in medieval times. Visitors can see how the structure's location reflects the importance of protecting these valuable resources.
The hike to the ruins follows a marked forest trail that winds from Hallein through wooded areas along the Antoniusweg and Dürrnberg-Landesstraße. Sturdy footwear is recommended as the path can be steep and muddy, especially after rain.
Between 2003 and 2008, the site underwent careful restoration work that brought together financial support from regional government, the city, national heritage authorities, and private donors. This collaborative effort preserved what remained and made it safer for visitors to explore.
