The medieval fortress of Enisala, located two kilometers from the village of the same name, is the last medieval fortress remaining in Dobruja.
Many questions still remain about who exactly built this 14th century fortress. Many experts suggest that it was the Genoese or the Byzantine Empire that built this structure. What we do know is that they had militaristic goals and wanted to monitor trade routes. In fact, during this era, Lake Razim was an important trade route, and the rocky hill of Enisala allowed for the monitoring of ships arriving in Gura Portitei. During this time Enisala was connected to the White Fortress (at the mouth of the Niestr River) and the Kilia Fortress (north of the delta).
Enisala was gradually restored by Mircea the Elder (Mircea Cel Batran), who then abandoned the fortress because it did not correspond with the strategic interests of the empire. This decision protected the fortress until the late 19th century, when the Russo-Turkish conflict in Dobuja led to the destruction of all medieval castles, which were taken by the Turks with the exception of Enisala.
