Built in the last two decades of the 19th century, under the Kingdom of Italy, the Forte di Monte Ricco constituted the heart of the entrenched camp of Pieve di Cadore. It was conceived and built to interdict enemy approaches from the Tre Ponti narrows towards Pieve and Tai along the Piave valley and to act in close synergy with the nearby Batteria Castello, about 200 meters away, as well as with the various artillery positions on the overlying heights, on Monte Tranego, Monte Zucco, Col Vidà. Monte Ricco was probably the site of a prehistoric settlement, then of the castle of Cadore. Abandoned until 2007, it has undergone demanding restoration, consolidation, and enhancement works. Reopened to the public in 2017, it hosts exhibitions or classical music concerts. https://www.tizianovecellio.it/luoghi/il-forte-di-monte-ricco/

The Forte di Monte Ricco, restored and reopened to the public in 2017, often hosts exhibitions and classical music concerts. However, it is advisable to call before visiting to check the opening of the main part. During a summer visit, in fact, it was found that access was allowed only by reservation. An entrance ticket is required but inexpensive. The Fort offers the possibility to walk around the front and internal perimeter, allowing appreciation of the pre-Roman structure. Protected by a moat and a drawbridge, the site also offers a panoramic view of Monte Cristallo. The Fort was built in the pre-Roman era with a defensive function, maintained also in Roman and medieval times. Before the year 1000, it was the seat of an important castle represented in the coat of arms of Cadore. From 1420 it became the seat of the Captain of Venice, but declined in the 17th century. During the Kingdom of Italy, two fortifications were built as part of the defensive system against Austria-Hungary. During the First World War, the Fort was relegated to a warehouse and logistics. Abandoned after 1918, restoration began in 2007 on the initiative of the Municipality of Pieve di Cadore, concluding in 2017.

Introduction: Beautiful and not excessively well-known mountain of the Tre Cime di Lavaredo group, which stands alone dominating the Rienza Valley and the Rinbon Valley. From the road that goes up to the Auronzo Refuge, it shows two neighboring horns, not particularly high and covered with pines. During the ascent and on the terrace of the summit, grassy and strewn with pine trees, numerous walkways and trenches dating back to the Great War are evident. Access: Just beyond the Malga (restaurant), reachable by car from the exit of the Tre Cime road following a short dirt road, which descends to the stream and leads to a large parking lot, a mule track branches off to the left and climbs into the woods. Description of the climb: In constant but not particularly steep ascent, you reach the panoramic grassy pass of Forcella de l´Arghena (altitude 2087 m), between the Croda on the left and the Col di Mezzo on the right. Evident remains of trenches, and boundary stone between the Tyrol and the Serenissima Republic. Traversing to the left in the direction of the left elevation, you oblique between the pines on the side of the Croda, to go up a short scree and, continuing on the path, skirt a ridge and move towards the top of the Croda. On the left (tab.) Junction for a short aided ledge, which leads to an interesting war tunnel. Going up still to the right, you pass a short rocky band (not equipped, 10 m of I) and among the pines you reach the wide cap.

The 'caves' around Auronzo di Cadore are predominantly historical war tunnels and galleries from World War I, rather than natural geological formations. These man-made structures offer a unique historical experience set within the stunning Dolomite landscapes.
Among the most popular are the Patern Galleries and War Trails, which are part of a beautiful via ferrata. Another highly regarded site is the Paternkofel Via Ferrata - De Luca Route, known for its challenging climb and historical significance.
While the region is known for its historical war tunnels, you can find the Mooser Cave and Trail in the Drei Zinnen Nature Park. This is a small natural cave, approximately 5 meters deep, located off the main path of the Anderter Alpe Open-Air Museum.
The best time to visit the historical war tunnels and sites, especially those around Tre Cime di Lavaredo, is typically from June to October when the mountain paths are generally clear of snow and accessible.
For tunnels like those on the Paternkofel, a headlamp or torch is essential due to complete darkness. Some sections, particularly those part of a via ferrata, may also require at least simple climbing equipment for safety, despite being secured by steel cables.
The Monte Piana Open-Air Museum offers a more accessible experience. It features a network of restored trenches, tunnels, and military posts on a plateau, providing an easy walk with panoramic views. It's a powerful 'museum without walls' that recounts WWI events.
Access to Monte Piana is possible via various paths. During summer, jeep services are available, and in winter, snowmobiles can transport visitors to the top. You can find more historical context about Monte Piana on Wikipedia.
Many of these sites offer spectacular panoramic views of the surrounding Dolomites. For example, Monte Piana provides a 360-degree vista of famous peaks like Tre Cime di Lavaredo, Paterno, and Cristallo, as well as Lake Misurina.
Yes, many war tunnels are integrated into hiking routes. For instance, the Tre Cime war caves are located along the 9 km Tre Cime circuit trek. You can find various running, MTB, and cycling routes in the area by exploring the running trails around Auronzo Di Cadore, MTB trails around Auronzo Di Cadore, and cycling routes around Auronzo Di Cadore.
The difficulty varies. Some tunnels, like those on the Paternkofel Via Ferrata, are considered challenging and require climbing equipment. Others, such as the Croda de l'Arghena War Tunnel, are part of intermediate trails. The Monte Piana Open-Air Museum offers easier walks.
While specific regulations for each site may vary, many outdoor trails in the Dolomites are dog-friendly. It's advisable to keep dogs on a leash, especially in areas with wildlife or steep terrain. Always check local signage.
Visitors often highlight the profound historical insight gained from exploring the WWI war tunnels and the breathtaking Dolomite scenery that serves as their backdrop. The combination of adventure, history, and stunning natural beauty is a major draw.
