The problem that had to be dealt with concerning the trees on the roof was to find out where their roots were directed without provoking the religious feeling of the church people and the clergymen that were our "sleepless guardians" throughout the entire survey.

After an onsite estimation of the situation it was decided that the high-frequency georadar would be used on the walls of the building together with electrical tomography using very small electrodes, so as to have a double check on the methodology.

It was proved that the roots follow the gaps existing inside the side stonemasonry walls creating repulsion stresses between the stones and thus they reach the ground.

This leads to the creation of a net of roots that reinforces the building from a static point of view opposing the roof load but is also destroying the stone walls.

The spring on top of Mount Tetrazion, the village's highest point, has water so cold that it's very hard for anyone to keep a hand in it for more than 40 seconds.

The legend has it that the god Apollo used to refresh himself at this spring as his temple is in sight at the mountain top on the west side below.
