Explore Enisala Fortress, a spectacular 14th-century Genoese stronghold perched on a hilltop commanding panoramic views over the Danube Delta and Razim Lake, where Italian merchants built this strategic fortress to control trade routes and protect their commercial interests in the Black Sea region. Climb the medieval walls and towers that have withstood centuries of weather and conflict, discovering residential quarters, defensive structures, and a small chapel that served the fortress garrison while learning about the complex medieval politics that brought Genoese traders to these remote shores. The fortress offers breathtaking views over Europe's largest wetland, where the Danube creates a maze of channels, lakes, and reed beds before reaching the sea, providing habitat for hundreds of bird species and creating one of the continent's most important ecological reserves that remains largely pristine despite centuries of human activity. The fortress is closed on Mondays, but is otherwise open 10 AM to 6 PM. There is an entry fee of around $2.50.
