While Nora has roots dating back to the Roman and even Hittite periods, its true peak occurred during the reign of the Byzantine Emperor Justinian I (6th Century). Justinian elevated Nora (Mokissos) to the status of a "metropolis," making it the ecclesiastical capital of the region.
The city was strategically located to oversee the trade and military routes crossing Central Anatolia. Its architecture is unique; instead of carving into the soft tuff, the builders used the hard andesite and basalt stones from the volcano to create durable, multi-story homes. This gives the city a distinct appearance compared to other Cappadocian sites.
The city was gradually abandoned after the 7th century due to Arab raids and a shift in regional security. Because it was "left behind" rather than destroyed, Nora offers archaeologists a rare opportunity to study a large-scale Byzantine city exactly as it was laid out in the 600s AD.
