Perched atop Dosso dei Galli in the Brescia Alps, the NATO Troposcatter Station IDGZ was a key telecommunications hub from 1969 to 1995. This station was part of the ACE High system, a crucial radio communication network that spanned from the northern to the southern reaches of NATO’s territory.
Historical Role
The IDGZ station linked the German Feldberg station to the north and the Italian Monte Giogo station to the south using advanced troposcatter technology. This technology allowed for robust and reliable communication, even when stations were out of direct line of sight and under adverse weather conditions. During the Cold War, the ACE High system, with IDGZ as a vital link, ensured fast and secure NATO communications.
Current Status
Although decommissioned in 1995, the remnants of the IDGZ station can still be visited from late spring through late fall (April to November) when the SP345 mountain pass road is open.
Visiting Tips
While the IDGZ station is administratively part of Bagolino municipality, it is situated about 20 kilometers away, with a direct distance of 8 kilometers. The journey involves navigating numerous switchbacks up the mountain.
Visitors should note that the entry gate is usually locked and blocked with boulders. You can park outside and take a 15-minute walk along a paved road to reach the remaining structures. These include radar dishes, bunk rooms, a power station, and a crow’s nest on the fourth floor. The site is accessible by road from April to November, subject to road conditions.
