Tuzla image - Bosnia and Herzegovina

Tuzla is a city and municipality in Bosnia and Herzegovina. It is the seat of the Tuzla Canton, and is the economic, scientific, cultural, educational, health and tourist centre of northeast Bosnia. After Sarajevo and Banja Luka, Tuzla is the third largest city in Bosnia and Herzegovina.

Tuzla is the only city in Europe that has a salt lake at its centre. The ancient Pannonian Sea dried up around 10 million years ago, but work by researchers and scientists has now enabled a level of saline water to be kept stable at the surface, and in 2003 the Pannonian Lake was opened.
