Nature and history have bestowed many things upon Bulgaria but islands, apparently, is not one of them
Still, this country does boast a number of small isles one of which is even permanently inhabited. Used intermittently as an Orthodox monastery, a prison and now a museum the small isle is known mainly for its lighthouse, though few locals imagine it was erected by the Ottoman authorities, back in the middle of the 19th century, as part of a grand project to modernise maritime navigation in the Black Sea. The isle can now be visited by commercial boats run by the local municipality.
