A 7500 mile journey across Asia along the old Silk Road

Great Kyz Kala is a gigantic early medieval building at Ancient Merv, built in the 6th-7th centuries AD along with Little Kyz Kala. The walls are built of mud brick. Archiologists believe they belonged to a rich landowner who possessed a number of similar 'castles' which stretched along the Khurmuzfarra Canal north for about 30 kms.
