Even higher at the top adobe bricks were used. Whether the adobe bricks had to be replaced every 70 years or so is not known to us. It is known that an adobe brick construction is durable especially if it is protected from dampness with a clay tile roof. The thing to note is that adobe bricks were used here which have since crumbled. Geological deposits of sea shells were from a Sarmatian era of paleontology.
Sarmatian limestone is one of numerous deposits of bygone millennia.
A discussion ensued during which course it was learned that an American team was working at a lake in the environs. The tour continued to the southern side of the fortification. Dr. Kutaisov pointed out the southwestern tower site, which was excavated in nineteen twenty nine. An imaginary line was drawn for us in the direction of the light house across the bay, which provided the locale for the once existing wall from the tower of which there only remained a depression consisting of rubble of the wall when it was disassembled in the 19th century in order to use the materials for the erection of a mosque. We continued along this depression to another fortification emplacement.
