Jajce | Bosnia and Herzegovina

Jajce functions as the primary historical and cultural node of Central Bosnia and is the former royal capital of the independent Kingdom of Bosnia. Situated at the confluence of the Pliva and Vrbas rivers, it serves as a specialized center for hydroelectric power generation, limestone-based heritage conservation, and eco-tourism. It is defined by its unique status as one of the few cities in the world with a high-volume waterfall in its urban center, its role as the birthplace of socialist Yugoslavia (AVNOJ), and its "egg-shaped" topography which gave the town its name.

Historical Timeline

Jajce was established as a fortress in the 14th century by Grand Duke Hrvoje Vukčić Hrvatinić. The primary era of governance was its tenure as the royal capital (1461–1463), where the last Bosnian king, Stjepan Tomašević, was crowned and later executed by the Ottomans. The primary event shaping its modern identity was the Second Session of AVNOJ in 1943, where the foundations of the Socialist Federal Republic of Yugoslavia were established. Historically, it was the last Bosnian stronghold to fall to Ottoman rule (1527).

Demographics & Population

The population of the town proper is approximately 7,200, with the municipality totaling 27,000 (2026 estimate). The demographic profile is balanced between Bosniaks and Croats, reflecting a return to multi-ethnic coexistence after the total evacuation and subsequent return of the population during the 1990s. The workforce is specialized in energy management (HPP Jajce I and II), tourism, and agriculture.

Facts & Legends

Jajce is the site where the last Bosnian king was crowned. Legend states that the town was named "Jajce" (egg) because it was built on a hill that resembles an egg, or because the mortar used for the fortress was mixed with thousands of eggs for strength. A verified fact is that the Pliva Waterfall is the only one in the world located in a city center that forms a perfect 90-degree drop into another river. Historically, the town was so prestigious that the Ottoman Sultans personally led sieges against its walls for decades before it finally capitulated.
