8 jun 500 año - Persians settled in the city & introduced major changes

Descripción:

They built the first city walls and developed the harbour as an important trading point. A moat was also dug around the city walls and filled with seawater. Hundreds of wells and cisterns were dug and constructed inside and around the walled city for daily water supply, and to increase the city’s resilience in case of siege.
