The Grotta Grande del Vento, the Great Cave of the Wind, is the most beautiful show of Europe. Okay, it is just my opinion, but I am not the only one who thinks so, and by the way: I have seen a lot of show caves in Europe.
Sometimes the beauty is explained with its late discovery. There is no history of centuries of visitors with torches and candles. But this is only part of the story. The cave is extremely big, the limestone very pure, the sinter grows fast and forms extraordinary speleothems of any kind. The special geology with sulfuric springs in the lower level gives the cave an additional boost, with solution by sulfuric acid and the formation of gypsum based minerals.
After the cave was discovered, it was rather immediately developed. This was done very careful and the lighting was set up by the well-known set designer Cesarini from Senigallia. A bit strange is the repeated use of blue light, which is rather unusual. Normally coloured light in caves is kitschy. But the extremely bright formations get a really bright shine with this blueish light.

The visit to the cave starts at Genga Statione, about two kilometers from the cave entrance. Here is the "bigletteria" (ticket office) and the parking lot. When you paid for your ticket, you have to wait for the bus. Of course, if you prefer to walk, it is only two kilometers, about half an hour, and there is a well prepared path with modern art and sulfuric springs for the last kilometre, from San Vittorio to the cave entrance.

The artificial entrance tunnel brings the visitors into a huge chamber with big stalagmites in the middle, looking like dwarfs in this enormous void. This is Abisso Ancona (Ancona Abyss), named by the speleologists from Ancona. The natural entrance to the cave is much higher up the limestone cliff and the passage behind this entrance meets this hall near the ceiling. So, from the explorers view, this was an abyss. Todays visitor would say it is a huge hall, as he enters it at the bottom.
The explorers had to abseil into this hall, where normal caving light was not able to even show a glimpse of the wall. So after leaving the shaft of the first few meters, they were hanging in the darkness, right in the middle of nowhere. The first of the group had no way to see the floor, until he hit it. And of course, after each expedition, they had to climb up the rope again.
|Image: a detail of the palm trunc stalagites.|
The stalagmites in Abisso Ancona are typical palm trunc stalagmites. The water falling from the high ceiling has a high energy, which results in this different shape of the stalagmites, looking like palm truncs.
|Image: cave lakes in the last part of the tour, the Sala dell'infinito (Hall Without End).|
After leaving the Ancona Abyss, the visitor enters a main passage of the cave with enormous amounts of speleothems. In the Sala delle candeline, a number of rather small, slim and pure white stalagmites stands in a calm cave lake. At the bottom, the formations are covered with dogtooth spar, calcite crystals that grew in thousands of years under water in a clear, absolutely undisturbed cave lake. The upper boundary of the crystals is absolutely horizontal, as it marks the water level of this ancient lake.
Some of those pure lakes still exist, and the calcite crystals are still growing. Others are mostly dry, but horizontal layers of crystals mark the original water level. And what looks like a plain floor, is only a thin crust of calcite, so fragile it would break in if touched by a human foot.
