How long didit take to rebuild Greece after pmpei and Athens 1600 years ago?

The rebuilding of Greece after the devastation caused by the Plague of Justinian in the 6th century and the subsequent decline, including the fall of Athens, took several centuries. By the time of the Byzantine Empire's consolidation, particularly around the 9th century, some areas began to recover, but the full revitalization of urban centers and infrastructure took until the late Middle Ages. The process was gradual, influenced by various political, economic, and social factors, making it difficult to pinpoint an exact timeframe for complete recovery.
