Guardian of the passage between the Dednik Hill and the Tolsti vrh Peak.

Only 2 km to the west of the Gradišče near Rob barrier in the village of Selo, there lie the remains of a barrier wall and towers. The Selo pri Robu barrier controlled the passage across the ridge between the Dednik Hill in the northeast and the Tolsti vrh Peak in the north, which led through the village towards the Bloke Plateau (Bloška planota).

The barrier, which begins under the peak of the Grič Hill, is preserved in the length of 396 m and runs in the direction from the southwest to the northeast. On a rather steep slope, it descends through a forest into a ravine, where it reaches its lowest point. From there, it ascends steeply to the opposite slope. At the top of the slope, it reaches its highest point on the present-day main road. The wall continues beyond the road, east of the present-day house, and ends over the precipitous slope.

In addition to the wall, two towers are preserved as well. The first, which is clearly visible and measures 5.5 x 5.7 m, stands directly by the main road and was most likely placed on the outer (northern) side of the wall. The tower is preserved approximately 1.5 m in height and has a clearly visible entrance. The second tower is much more ruined and stands on the other side of the road, where the wall continues in the vicinity of the present-day house.
