Pyu Ancient Cities includes the remains of three brick, walled and moated cities of Halin, Beikthano and Sri Ksetra located in vast irrigated landscapes in the dry zone of the Ayeyarwady (Irrawaddy) River basin. They reflect the Pyu Kingdoms that flourished for over 1,000 years between 200 BC and AD 900. The three cities are partly excavated archaeological sites.
