The Didivan tower is erected on a high hill near
Khanliglar village. It is assumed that the tower was built
in the VI-VII centuries. It is round in shape. The frame of
the fortress narrow upwards. Inside it is empty. However,
you can see holes for he woods that once made of coverage of
storeys. Intervals between the storeys are not equal in
size. Height of the fortress is 8.3 m, inner diameter 5.85
and thickness of the walls in the lower part 1 m. Didivan
tower served as defence and guard installation in the past.
Its high location made it possible to control other defence
installations and dwelling places around and quickly inform
about imminent danger. This type of medieval observation
points are also existed in the valley of Choqaz river and
near the Jafarli village.
