The moment of discovery was particularly impressive for the underwater archaeologists. Diving in Lake Neuchâtel, Fabien Langenegger and Julien Pfyffer made a spectacular discovery from the Roman Empire.
"At first, we both cautiously approached this pile of circles, which could have been a depot of mines left behind from the Second World War. But when I switched on my camera light, the characteristic colour of terracotta emerged. Looking at some broken plates, we realised that this find was extraordinary."
