Overview
Iconic limestone arch collapsed into the sea in 2017, leaving an underwater field of car-sized boulders between 15 and 50 m. Now one of the more dramatic geology dives in the Med. The collapsed pillar stands like a fallen monument on the bottom.

Sources & methodology
How we summarise this
We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
