Rostov-on-Don
Rostov-on-Don was founded in 1749. In that year, a customs house was built on the Don. Later, a large fortress followed. It was named after Saint Dimitry of Rostov. Dmitry of Rostov was a bishop from the old Northern town Rostov the Great. With the time, the importance of the fortress Asov became less and less. The settlement near the fortress became more important than the fortress. It was the commercial centre of the region. In 1796 this settlement received city rights and was renamed Rostov-on-Don.
