On the light vault a stalactite 7.40 m long called the sword of Damocle and communication trenches connecting upstairs cave floors. In front of the tourist (in march way) there is a signle and impressive obelisk. It has always been a datum point for all the speleologists that have been operating here. This stalagmite has as base a wide rock fallen from the ceiling and it is about 15 m. high. On the side, in a cave's corner, the toursit find a colourful palette: white, ferric red, pink with light grey dued to the manganese oxide.
