In 1848–1849, a Russian marine expedition of the Aral Sea was organized with the schooner
Konstantin, commanded by naval officer and investigator A. I. Butakov. One of the members who served as the expedition's artist was
Taras Shevchenko. A group of islands was discovered that were named the Tzar Islands, consisting of
Nicholas I Island, Konstantin Island and Naslednik Island. In the Soviet period Nicholas I Island was renamed Vozrozhdeniya. In the 1920s, leaders of the
Red Army were searching for an appropriate place to build a science and military complex for inventing, producing, and testing biological weapons. An ideal location for such complex would be a relatively large island from a coast. Initial sites discussed for this complex included
Lake Baikal, but choices were narrowed down to the
Solovetsky Islands in the White Sea,
Gorodomlya Island located on
Lake Seliger and Vozrozhdeniya Island. In 1948, a top-secret Soviet
bioweapons laboratory was established on the island, which tested a variety of agents, including
anthrax,
smallpox,
plague,
brucellosis, and
tularemia. In 1954, the site was expanded and named Aralsk-7, one of the main laboratories and testing sites for the
Soviet Union's Microbiological Warfare Group, tasked with inventing and testing the effects of multiple fatal diseases. In the earlier 1990s, word of the island's danger was spread in the west, first by Soviet defector Vladimir Pasechnik, and later by
Ken Alibek, the former head of the Soviet Union's bioweapons program. According to released documents,
anthrax spores and
bubonic plague bacilli were made into weapons and stored at the complex. The main town on the island, where scientists and employees of the complex lived, was called
Kantubek, which lies in ruins today, but once held approximately 1,500 inhabitants. The official Soviet name of this city was the same as the weapons complex itself: Aralsk-7. All people who lived on Vozrozhdeniya Island were evacuated within several weeks; civil and military infrastructure was abandoned, and Kantubek became a
ghost town. ==In popular culture==
