Kozlov rob, which the locals like to call Grad (Castle), is of incredible cultural-historical importance and a popular recreation spot in the Tolmin basin. If you want to combine a bit of exercise with discovering history, step onto a trail that uncovers the periods of the Tolminsko from the 12th century onwards.
A dome-shaped hill with a beautiful view over Tolmin and a castle building from the 12th century.
The castle building, which was first mentioned in the 12th century, was owned by the patriarchs of Aquileia, the counts of Gorizia, inhabitants of Cividale del Friuli, Venetians and Habsburgs. Because the castle, now declared a cultural monument, changed owners many times through the centuries, its architectural image changed too, particularly after the major earthquakes of 1348 and 1511. It was last renovated by the Dornbergs in 1608.
In the second half of the 17th century, under the rule of the Coronini family, the castle was abandoned. The owners moved to a new building in Tolmin, where Tolmin Museum stands today. The castle ruins have been in the process of gradual renovation for the past few years. A part of the castle wall and St Martin’s chapel have already been renovated.
The history and natural history educational path lies on the southern slope of Kozlov rob and presents the flora, the structure of the forest ground and rocks, as well as interesting historical events at fourteen points.

Kozlov rob Interpretation Centre
Kozlov rob Interpretation Centre takes visitors into the story of one of the most important castles in the Primorska region, which has watched over the Tolmin Basin for centuries.
On this panoramic hill, where the area was already controlled by Iron Age inhabitants and the Romans, a modern exhibition now brings to life the development of the castle, life in Tolmin, and the rich cultural heritage of the area.
A permanent exhibition by the Tolmin Museum has been set up in part of the restored castle ruins. A special experience is offered by the multimedia “immersive room”, which presents the history of Kozlov rob in a contemporary way.
An additional experience is available through the gamified experience “Little Goat on a Mission: Let’s Preserve Kozlov rob”.
You can enhance your visit with a guided tour along the Trail of Three Castle Buildings, which connects Kozlov rob, the Coronini Mansion, and the court of the Patriarch of Aquileia at Dor.
In addition to views of the Tolmin Basin and the surrounding peaks, Kozlov rob invites you to explore the stories that have shaped life in the Soča Valley through the centuries.
Immerse yourself in castle heritage and discover the stories hidden by Kozlov rob.
