Turkmenistan - State Historical and Cultural Park "Ancient Merv"

"Merv is the oldest and best-preserved of the oasis-cities along the Silk Route in Central Asia. The remains in this vast oasis span 4,000 years of human history. A number of monuments are still visible, particularly from the last two millennia.”
