Watch HDToday. The city of Mariupolis is by the Azov sea. It is also on the river Kalmius. Most of the city’s residents, half a million according to the last census, are working for the steel factory and do fishing, for leisure or food, in between shifts. The orthodox church towers above the city and its newly build bronze domes are sitting next to it, waiting to be donned. A tent near by is sheltering a crying icon, which receives a steady flow of visitors.
