Horezm is a fertile oasis located in lower reaches of Amudariya river that flows between Karakum desert and Kyzylkum desert. Horezm is a land of ancient civilizations. The "Father of History" - ancient Greek Herodotus - was calling Khorezm as "country of a thousand of fortresses".
This was the land of irrigated farming. Remains of ancient canals up to 90(!) km long from second half of 1st millennium BC still can be found in the today’s desert of Kyzylkum. Hundreds of ancient fortresses are also found there in the desert where once, hundreds of years ago, Amudaria river flew changing its course regularly and living ancient towns and settlements abandoned.
