Theopetra Cave can be found on the NE side of the big rock that lies at the right hand of the road which leads from Trikala to Kalambaka. The cave was inhabited for the first time in the Middle Paleolithic period and was used continually until the end of Neolithic period. From the neolithic phase there is beautiful pottery, typically thessalian, as well as flint implements and bone tools, other clay objects and a wall made of stone. From the paleolithic phase, upper and middle, there are also flint implements and bone tools which characterize the period. Animal species that are represented in the bone material are sheep and goat, cow, pig, deer, dog, badger, hare and tortoise. There are also some human bones. C14 analysis has given a date about 38.000 B.P., but this is not from the deepest levels of the cave.
