Opera 1 bis

Opera 1 bis is a military bunker located in northern Italy, near the town of Cortina d'Ampezzo in the Veneto region. The site is situated in the Dolomite Alps, a mountainous area that has historically been of strategic military importance due to its proximity to the Austrian border. The bunker's exact construction date and purpose remain unclear from available sources, but its location suggests it may have been part of Italy's defensive network during the Cold War era or earlier conflicts in the region.
