Ayaz Kala, Ancient Khorezm

The biggest fortress is built on the top of a hill overlooking the vast Amu Darya plain. It is the oldest part of the fortress.
Down the hill stands the palace of "King Afrig", from where a suspension bridge was supposed to led up to a close rock, where it still remains a little citadel that once protected the palace.
These buildings were used as a fortress aiming at providing shelter to the numerous population of the fertile plains till the Arabs invaded the place at the 7th century.
