The inflow of water from the aquifer was a frequent problem during the mining process. This problem was addressed by pumping out the water. Where it was impossible to continue mining, the galleries were abandoned or sealed. Upon completion of the work, the inflow of water flooded the lower levels, making them inaccessible. The water prevented visitors from accessing these lower levels, protecting this section of the mine from vandalism.

The discovery of such a flooded arcade and the need for further exploration led the Addicted2H2O diving team and Cave Divers Erikos Kranidiotis and Stelios Stamatakis to explore these galleries further. From July 2019 to December of 2020, exploratory dives have been carried out in several sections of the mines at Plaka and Agios Konstantinos sites, capturing video footage of these underwater galleries for the first time.

Underwater exploration of these arcades give us a different dimension to the way we now view the Lavrio mines, providing us with a unique insight of the galleries from their last day of operation. A completely different dimension is also given to the various types of underwater exploration projects taking place in Greece. Adding the Greek Mines to the domestic and international dive forum communities.

During the course of this project we met quite a few people along the way. People with different backgrounds who all worked together towards a common goal which was non other than to discover what is hidden underwater in these mines. Offering their help voluntarily and in most cases operating under difficult and tiring conditions. We would like to thank every single one including those people from the press who were interested to share our story. We feel humbled and honored by the support we received from everyone.
