Salona was an ancient city and the capital of the Roman province of Dalmatia. The name Salona preserves the language of the early inhabitants of this area whom the Romans called Dalmatae, and considered to be part of a larger group called Illyrians.

Klis is a Croatian town located around a mountain fortress bearing the same name. It is located in the region of Dalmatia, located just northeast of Solin and Split near the eponymous mountain pass. It has a population of 2,621, totalling 4,421 together with the eight other villages in its municipality (census 2001).The Klis mountain pass separates the mountains Mosor and Kozjak at the altitude of 360m. It has had a major strategic value throughout history, because any inland force passing through Klis would have been able to easily reach the entire region of Split and Kaštela. During the Ottoman wars in Europe, an already existing Roman fortress on a nearby hill was expanded into Klis Fortress. It was the centre of a sanjak within the Province of Bosnia during Ottoman rule. Klis was also ruled by Kingdom of Bosnia, Venetian Republic and Austria-Hungary. Due to its geographical position, Klis is also susceptible to a rather strong bura wind.
