Enisala

Enisala's fortress rises above the waters of Razelm and Babadag in northern Dobruja. When it was built in the late thirteenth or early fourteenth century, these lakes were still gulfs open towards the Black Sea. Its walls guarded routes through the region, and three hexagonal towers gave the stronghold a form unlike others in Dobruja. The Ottomans first captured the castle in 1388 or 1389 and retook it after a period of Wallachian rule. As sand spits developed and obstructed maritime trade, the fortress lost its former value and gradually fell into disuse. By the end of the fifteenth century its garrison had abandoned the hill above the changing waters.
