Ashdod is the sixth-largest city and the largest port in Israel accounting for 60% of the country's imported goods. Ashdod is located in the Southern District of the country, on the Mediterranean coast where it is situated between Tel Aviv to the North and Ashkelon to the South. Jerusalem is 53 km to the east. The city is also an important regional industrial center. Modern Ashdod covers the territory of two ancient twin towns, one inland and one on the coast, which were for most of their history two separate entities, connected by close ties with each other. This article deals with these historic towns, including other ancient nearby sites, and modern Ashdod.
