<< On the rocky shore of Paleokastro and in the sea in a bay called Bad River, there is a cave carved into the hard rock (also called Pelekiti).
It is unknown when this cave was built and for what purposes it was made, but its construction is symmetrical.
It is perfectly preserved despite the centuries that have passed since then and the hits it has received for centuries from the waves of the sea.
This cave is blocked at the bottom with the rock, but apparently, it communicates with another inner cave through a small hole, as it is observed lower in the sea at the bottom of the cave.
The shape of the small window observed at the bottom of the cave and in the sea is triangular and is under water. The cave has a parallelepiped shape, and its dimensions are the following: length about 13 meters, width 2m. 40cm., Height in the middle of the cave 3m. 40cm about half of it is under water.
This phenomenon of this cave, more than half of which is found under the sea water, proves, as mentioned above, that the territory of the island of Kimolos suffered at a time very distant from the current one, lowered by either seismic or a volcanic explosion.
The same phenomenon is also observed in the area of Ellinika, in part of the ancient city of Kimolos, due to landslides, disappeared under the sea, as already mentioned above in the chapter on the necropolis of the Ellinika.
The cave communicates with the sea and is visited only by sea and by boat, that enters freely into the cave. Near the innermost depth of the cave, on the roof there is a stone arch in the shape of an arch, well preserved to this day.
On the walls of the cave, there are seven carved squares inside the rock, three of which are on the left side, and four on the right. One of the carved squares on the left side carved on the hard rock has the shape of a very regular square whose dimensions are as follows, length 3m. 40cm., Height 1m. 10cm and depth inside the wall 0m. 40cm. The latter excavation is above the surface of the sea, while the others have been carved into the rock and at the height of the sea. The hardness of these excavations cannot be determined.
My opinion is that this cave, as well as that of Bromolimni, was used in ancient times for the residence of inhabitants of Paleokastro, as a nomadic life or as a family grave of a family member within it. . >>
