8. Gruinard Island
Just North of Scotland, Gruinard Island was once home to a small town and its inhabitants. But during the Second World War, it was ‘acquired’ by the British government for use in developing and testing biological weapons, specifically anthrax.
The tests included dropping anthrax filled bombs on sheep that were left on the island for that purpose. In 1945, the Ministry of Supply deemed it unfit for human or animal habitation. By that time, contaminated soil from the island had started to wash towards mainland Scotland.
In the 1980s, the government tried to decontaminate the island by spraying tonnes of seawater and formaldehyde to kill any remaining bacteria spores. This treatment only succeeded in ‘cleaning’ the top soil of the island. Who knows what lies a few feet under? Despite this, the land was declared safe in 1997.
