🪑 Panoramic bench on the border ridge The bench is located on the ridge east of the summit, near Glava (1519 m), exactly on the Italian-Slovenian border. The view looks south over the Natisone valleys and the Friulian plain to the Gulf of Trieste, about 50 km away. In clear weather, the lagoon of Grado and the coast towards Trieste can be seen, and to the west, the hills of Cividale and Udine. A perfect spot for the first break after the descent.

This mountain is part of the Mia-Lubia-Matajur anticline, a transition area between the Southern Alps and the Dinarides, with sedimentary formations from the Lias (Jurassic) to the Upper Cretaceous, which were deposited between 212 and 65 million years ago. Due to its location (summit at 1641 m above sea level), alpine, Balkan and sub-Mediterranean flora meet and merge here. Above 1300 meters, the landscape offers wide, little-grazed meadows with natural primary herbaceous species that have grown after the removal of the original beech forests.

A former border station, a classic example of modern architecture, having become obsolete due to the expansion of EU member states. On the Italian side, the border building is very well preserved and used by the Alpini (Italian mountain troops), while the Slovenian building is dilapidated. On the Italian side, there is also a monument to a distinguished Alpini soldier.

The entire Kolovrat Ridge was a theater of World War I. At 1,115 meters above sea level, the "Third Italian Defense Line" was established, which played a key role during the Battle of the Isonzo. Many of the paths and positions have been restored to their original condition, so that the trenches, positions, and fortifications now form a free, accessible open-air museum for everyone. The open-air museum also features a small hill serving as a viewing platform. From here, breathtaking views of the valley to Tolmin, the Soca River, and the surrounding mountains are offered.
