Tuida Fortress

The ruins of the early-Byzatine fortress Tuida are spread over an area of 40,000 sq.m on the Hisarlaka hill in the Northeastern part of the town of Sliven (East Balkan Mountain). Later the fortress was known as Tsoida and Soida. It was constructed probably in the second half of 4th century. The archeologists have found here tools and ancient-Greek inscriptions proving the existence of a Zeus-dedicated sanctuary. A seal of King Boris Mihail was also found here. In 13th century the fortress was abandoned and never used again. Today, the visitors may see the fortified walls, the four circle towers with semicircle antechambers, two rectangular towers – gates, the foundations of an administrative building, a basilica, as well as fragments of mosaic and different tools and coins, protected in the Sliven Museum of History. The castle is open for visitors on December 22, 2014, after modernization within the project for over BGN 5 million (Pfoto: tuidacastle.sliven.bg)
