Extreme toilet in Serbia
Imagine the pizzazz you need for a night time dash to this precarious privy perched on the edge of a sheer cliff some 2,600 metres above sea...

This loo with a view serves the remote weather station at Kara-Tyurek - literally Black Heart in the local South Altayan language - which began working in 1939. Five staff man the station at this outpost, and this is their only toilet.
They are visited once a month by a postman to collect the weather data, and a helicopter delivers supplies of food and water each autumn. Wood too, to burn on the stove, because there are no trees in this bleak landscape.
A recent survey of privies with panache by Interfax news agency in Belarus explained: 'The toilet is perhaps the most unromantic place possible, but there are some parts of the world where people have made them something really special.' This Siberian commode was listed as the 'most extreme' in the world where the fear evaporates only after years using it.
