Tuzla is a town in north-eastern Bosnia, known for its salt and coal mines and its chemical industry. With records of its existence dating back as far as one millennium, Tuzla has been known under this name (tuz=salt in Turkish) some 500 years. Its first, still existing mosque was built 1545.

In addition to its industries, Tuzla is an  educational and cultural centre of Tuzla-Podrinje Canton, with a university and a 100 year old theatre, the oldest in Bosnia-Herzegovina.

In 1990 elections, Tuzla was the only town in BH in which non-nationalist parties won. Its multiethnic and multicultural character was preserved throughout the hardest days of the war. The Cemetery 25 May, with the graves of 71 young victims, killed by just one shell on 25 May 1995, belonging to all nations and religions, inseparable in death as they were in life, bears testimony to this surviving belief that we could and can live together.

Despite its hardships during the war, Tuzla remained open for everybody  with good will. This resulted in very good relations with many cities all over the world: the first twining made with Bologna, Italy, in 1994; in 1996 with Hospitalet, Catalonia and Osijek, Croatia. (more about Tuzla)
