VALLO ALPINO - BLOCKADE

"CANONLA"

Canonla - Idria di sotto

XXII. Sector (Idria), Subsector XXII. B.(Idria)

Sbarramento "Canonla" (Kanomlja) - Official designation "Bevilacqua"

Situated near the town of Idria di Sotto (Spodnja Idrija), defending the entrance of the Canonla valley with the road towards West. Consists of three (?) separate forts, two constructed above the ground as massive concrete structures and one underground. Also, a number of field HMG and LMG positions, as well as passive AT defences including AT wall and minefields. At least two separate concrete observatories - LMG positions on both sides of the river.

Official complement including 116 enlisted men with 2 officers.

Armament: 9 HMGs, 5 LMGs, one 47/32 mm AT gun, two 81 mm mortars.

 

Fort No. 1: Underground fort on a ridge on the left bank of the river, with one steel observatory cloche (osservatorio attivo), and two HMG positions. Since I haven`t been able to find the entrance, the fort`s inner layout remains undescribed.

Fort No. 2: Left bank of Canonla, immediately below fort No. 1, consisting of one concrete structure armed with two HMGs behind "armour in three parts". One caserne situated in the main structure, with ammo, food and water storages. Photophone for communication with fort No. 3, with a narrow safety exit below it. Another photophone oriented Westwards, but I was unable to locate any fort there. Furthermore, since fort No. 1 is situated above it (not to the West), it is unclear whether the photophone was used for communication with some other position (or, for instance, barracks...). Gas-proof doors and air regenerator for anti-gas defence.

Fort No. 3: S side of the road, right bank of Canonla, consisting of a concrete structure armed with two HMGs behind "armours in three parts". One caserne situated in the main structure, with ammo, food and water storages. Photophone for communication with fort No. 2. Gas-proof doors and air regenerator for anti-gas defence. Separate safety exit.


Present state of the forts:

according to the locals, the entrance of fort No. 1 was closed due to building of the water reservoir in its vicinity. Forts No. 2 and 3, as well as smaller structures preserved and more or less accessible (dirtiness being the standard problem of "accessible" bunkers). One has to climb rather steep hillside to gain access to Fort No. 2, and fort No. 3 can be reached only over privately owned land (surrounded by low-voltage electric fence of a sheep pasture), so one has to ask the owners (nice people) to disconnect it. Gas-proof doors, electrical and other outfittings are removed. The forts are generally in very good condition.
