Dvuyakornaya Cove, Natural cove on the Black Sea coast, Republic of Crimea.

Dvuyakornaya Cove is a natural inlet along the southeastern Crimean shoreline, marked by rocky cliffs that drop toward the Black Sea. The waters here are relatively clear and provide habitat for diverse marine organisms and bottom-dwelling life forms.

In 1784 an artillery battery, the Dvuyakornaya, was stationed in the cove. On its shore stood the dacha of the Russian shipbuilding engineer G. I. Bubnov, around which grew Bubnovka, a small summer settlement of the Russian intelligentsia. The cove's name origin is not fully established; one version holds that Venetian ships had to drop two anchors at once during strong winter storms.

The name's origin is uncertain; one account holds that Venetian ships had to drop two anchors at once to hold position during strong winter storms. Near the altar of a ruined Armenian church within the cove, inscriptions in Armenian letters were found. The shore settlement Bubnovka grew around the dacha of shipbuilding engineer G. I. Bubnov.

The cove lies south of Feodosia between Cape Ilya and the Kiik-Atlama peninsula, reached by a valley between the Tepe-Oba and Biyuk-Yanyshar ridges. Its shores are mostly high and steep, and the bay is about 7.5 km wide. Meltwater and rain from the mountains run into it in spring.

Scientists have discovered numerous diatom species in these waters, including several previously unknown to science. These findings make the location particularly valuable for marine biology and the study of microscopic organisms.
