Descend into the depths. This is the Pozzo presso la Stazione ferroviaria di Villa Opicina. A seemingly unremarkable opening. Yet this shaft holds secrets. It hides a history stretching back to the explorations of the Commissione Grotte.
The Pozzo presso la Stazione ferroviaria di Villa Opicina is more than just a hole in the ground. It’s a 112-meter-deep abyss. It’s a testament to the Carso Triestino’s karst landscape. This remarkable geological formation dominates Trieste. This specific pozzo is cataloged as number 55 in the regional cave registry. Its entrance is easily accessible. It lies just 50 meters from a wide cart track. The track begins at a turnout from the SP9 road. The road runs from Opicina toward Monrupino. It’s near the former Ristorante Daneu.
The pozzo’s mouth is nearly two meters wide. Initially explored long ago its lower sections are now impassable. Debris has completely blocked the way. Recent attempts to clear the passage have failed. The inner shaft’s narrow opening remains elusive. Explorers once found this part of the cave perilous. The rock is extremely fragile.
A 1986 update reveals more details. The initial 32-meter shaft is quite wide. Its gray walls are smooth. There are no formations. Deep grooves mark the walls. At 5 meters down a large fissure runs the length of the shaft. It continues into the terminal cave. The outer shaft drops into a second shaft. The two shafts are connected by a narrow vertical passage.
Below this passage is a small chamber. The chamber floor slopes upward. It’s easy to reach. The main shaft continues. It descends another 20 meters widening as it goes. At 55 meters deep a platform of large boulders appears. Various openings lead to the lower 41-meter shaft.
This deep shaft near the Villa Opicina train station offers a glimpse into the hidden world beneath Trieste. The Pozzo presso la Stazione ferroviaria di Villa Opicina is a captivating reminder of the region’s geological wonders. It’s a challenge to those seeking adventure. A testament to nature’s enduring power. It whispers tales of past explorations. It beckons those brave enough to venture into the unknown.
