Explore Enisala Fortress (Cetatea Enisala), a magnificent 14th-century Genoese fortress built on a hilltop overlooking the Danube Delta and Razim Lake, offering some of Romania's most spectacular panoramic views over wetlands that stretch to the horizon. Climb the well-preserved medieval walls and towers that once guarded the strategic entrance to the Danube River, controlling trade routes between the Black Sea and the interior of Europe while protecting Genoese commercial interests in this crucial waterway. Walk through the fortress ruins discovering the chapel, residential quarters, and defensive structures that tell the story of medieval military architecture and the complex political relationships between Italian trading republics, Byzantine Empire, and emerging Romanian principalities. Learn about the fortress's role in controlling access to the Danube Delta's rich fishing grounds and trade routes, while enjoying breathtaking views over the largest wetland in Europe where the Danube splits into multiple channels before reaching the Black Sea. The site offers excellent opportunities for photography, especially during sunset when the golden light illuminates the delta's maze of waterways and reed beds that provide habitat for over 300 bird species, making this fortress not only a historical treasure but also a gateway to understanding the natural wonders of the Danube Delta, Europe's last great wilderness that has remained largely unchanged for millennia and continues to serve as a crucial stopping point for migratory birds traveling between Arctic breeding grounds and African wintering areas. The fortress is closed on Mondays, but is otherwise open 10 AM to 6 PM. There is an entry fee of around $2.50.
