The fortress Semionovskaya (Russian, Семёновская крепость) was a fortress, located in the territory of the present Selwo Beglitsa of Rostov Oblast of the south of Russia, defending the mouth of the Miús liman in the Taganrog Gulf of the Sea of Azov. It was on the left bank of the liman and was in use between the end of the seventeenth century and the beginning of the eighteenth century. History
In 1674 was sent from Moscow to Don the voivode prince Piotr Jovanski-Zmei with the order to build a fortress at the mouth of the river Miús. When it did not find a suitable site for the construction the idea would be abandoned until 1698 when the construction of the fortress, called Miyus (Миюс), would be carried out. Later it would be renamed as Semionovskaya fort.
The building had the shape of an irregular rectangle with 4 towers and 2 turrets, one of which protected the door, facing the steppe. The terraced terrain had a height of 3.5 m and a depth of 2 m, with a width of 6 m. In total a surface of 600 x 500 m was covered.
Since 1699, the garrison consisted of 421 people, including reiters, lancers, and soldiers. At that time, the Cossacks began to frequent the fortress, who came to register as traveling merchants. In 1711-1712 the fort was partially destroyed, as Russian troops withdrew as a result of the end of the Russo-Turkish war (1710-1711) (Prut Treaty).
In the 21st century, the outline of the ruins of the fortress is visible along with the limestone Mius, eroded by the sea. A number of archaeological and historical studies and studies have been carried out which have found remains of ceramics and pipes. and
