A stop most people walk right past
If you've done my walk along the coast toward Stoja, you've probably passed a small monument without really noticing it. No crowds, no souvenir stands, just a plain marker near the sea. I always slow down here, and I usually tell people: this spot has one of the heaviest stories in Pula, even though almost nothing about the place itself announces it.
This is Vergarolla.
What happened on 18 August 1946
In the summer of 1946, Pula was still reeling from the war, caught in the uncertain period before the city's final status was settled. Vergarolla beach was a popular spot, and that day it was hosting a swimming regatta, a local sporting event that had drawn families, children, athletes, a real community gathering by the sea.
Near the beach, stacks of old wartime ordnance, mines and munitions left over from the conflict, had been piled up, reportedly awaiting disposal. Sometime that morning, this ordnance detonated. The explosion was enormous. It tore through the crowd gathered for the regatta and left devastation along the whole stretch of shoreline.
The death toll is one of the things I'm careful about when I tell this story, because the sources genuinely don't agree. Estimates I've seen in different histories range roughly from the mid-sixties into the hundreds, depending on the source and how they counted the missing versus the confirmed dead. I don't pretend there's one clean number. What's certain is that it was mass casualty, entire families lost in a single morning, and it remains one of the worst single disasters in the city's twentieth-century history.
Why the cause is still debated
People often ask me, straight up: was it an accident, or was it deliberate? And I tell them honestly, I don't know, and neither does anyone else with full certainty. Historians have put forward different theories over the decades, some pointing to an accidental detonation of poorly stored munitions, others suggesting sabotage connected to the tense political situation of the time. No investigation ever produced a conclusive, universally accepted answer. I'm not going to stand at that monument and tell you a version I can't back up. What I can tell you is that the uncertainty itself is part of the history, and it's part of why the event still carries such weight.
Why it matters beyond the explosion itself
Vergarolla didn't happen in isolation. It came right in the middle of the years when Istria's Italian community was living through enormous upheaval, as the region's postwar borders and future were being decided. For many of the Italian families who had deep roots here, the disaster became tied up with fear, grief, and the decision many made soon after to leave, part of the broader and still painfully debated history of the Istrian-Dalmatian exodus.
I try to be careful here, because this is genuinely contested terrain, and different communities and families carry different memories and different conclusions about that period. My job isn't to hand you a verdict on decades of complicated history. It's to make sure you know this happened, that real people with names and families were killed on an ordinary summer morning, and that the quiet monument you're standing next to is there because people wanted it remembered.
Why I still stop there
I'm not a historian by training, I came to this through years of reading, listening to people in Pula who grew up with this story in their families, and guiding visitors who sometimes know more about one angle of it than I do. What I've learned is that respect means telling you what's solid, flagging what's disputed, and not flattening a tragedy into a tidy narrative just because tidy narratives make for a better stop on a walking tour.
So when we reach that part of the coast, we stop, we read the inscription together, and we talk about what's known and what isn't. It's one of the quieter moments on the walk, but for me, it's one of the ones that matters most.
