The city of Taraz, located near the southern border with Uzbekistan, is one of the most significant historic settlements in Kazakhstan, and two seasons of fieldwork in the central market-place have revealed a substantial depth of medieval stratigraphy. Despite frequent mentions in Arabic and Chinese written sources, both the form and evolution of this important Silk Road city remain poorly understood. Evidence for a series of successive medieval buildings, including a bathhouse and a Zoroastrian flame shrine, was found in the area of the former citadel. These excavations, undertaken as a joint initiative between the Centre for Applied Archaeology and Kazakh archaeologists, were the first for 50 years in the city and form part of a wider public outreach programme.
