Bulgaria's Antarctic research base
Called “St. Kliment Ohridski”, it is in the eastern part of Livingston Island, South Shetland Islands.
Around 25 scientists work there during summer months, doing research work in areas such as geology, biology, glaciology and topography.
The base’s St Ivan Rilski Chapel is the world’s southernmost Eastern Orthodox church.
An office of the Bulgarian Posts has been operating there since 1994: postal code BG 1090.
