Poveglia is a small island located between Venice and the Lido in the Venetian Lagoon in northern Italy. Starting in 1776, for over 100 years it was used as a quarantine station for people suffering from the plague and other diseases, and then as a psychiatric hospital, which was closed in 1968. Since then, the island has remained abandoned.

On March 1, 1954, the first and most powerful (15-megaton) US hydrogen bomb, codenamed “Castle Bravo”, was detonated on Bikini Atoll.

The explosion turned out to be 8 times more powerful than expected, it caused widespread radioactive contamination near the lying territories. 23 Japanese sailors aboard a fishing boat were also in the affected area, one of them died in September 1954.


Miyakejima is a volcanic island in the Izu Archipelago in the Philippine Sea, about 180 kilometers southeast of Honshu, Japan. At its center lies the Oyama volcano.

As a result of the eruption of 2000, caused by an earthquake, poisonous volcanic gas began to seep from its crater. The entire population of the island was evacuated for a period of 4 years and 5 months.

But despite the completion of the evacuation and the opening of the tourist season, the release of gases from the crater does not stop until now.

Queimada Grande

Queimada Grande is a small island in the Atlantic Ocean, 35 km off the coast of the Brazilian state of Sao Paulo. It has an area of ​​about 0.43 km².

Known mainly due to the huge number of American spear-headed snakes (Bothrops insularis) inhabiting it, whose bite causes rapid tissue necrosis.

Due to the presence of so many reptiles, there are no mammals on the island. It is believed that about 430,000 individuals live here.

For this reason, as well as for the sake of preserving flora and fauna, the country’s authorities prohibit visiting the island, which is included in the list of the most dangerous places on Earth. Currently, only people with special permission can access it.

Ramri Island

A rather unpleasant story is connected with Ramri Island in Burma. During World War II, the Japanese were defeated by the British and tried to escape through the swamps of this island, but were attacked by combed crocodiles.

British soldier and naturalist Bruce Stanley Wright, who participated in the battle, reported that of the more than a thousand Japanese soldiers who were on the island, the British captured only 20 who were in a state of shock. The remaining 1215 were torn apart alive by crocodiles.

North Sentinel

North Sentinel is one of the Andaman Islands in the Bay of Bengal. The Sentinelese tribe lives here, which very aggressively rejects any contact with the outside world.

Their number in 2018 is estimated at 50-400 people. This is one of the last tribes that has not yet come into contact with civilization.

In order to prevent the natives from contracting diseases to which they are not immune, the Government of India has declared the island and its surrounding water area a restricted area.

Renaissance Island

Vozrozhdeniye Island is a former island, now a peninsula in the southwestern part of the Aral Sea. Territorially divided between Kazakhstan and Uzbekistan.

From 1948 to 1991, a secret Soviet biochemical laboratory operated here, where, according to unconfirmed reports, bacteriological weapons were tested (including anthrax, smallpox, plague, brucellosis and tularemia).

However, when in the 1990s information about the danger of the island was declassified by one of the Soviet defectors, all the people living on the island (about 1500 people) were evacuated; civilian and military infrastructure were abandoned and Kantubek became a ghost town.

It is striking that many of the containers containing biological agents were not even properly buried or destroyed until 2002.
