In the 9th century, Nin stood as Croatia's first royal capital, where seven kings were crowned on the sacred grounds of the Roman Forum
Nin — The Kings' Broken Oath
You are Bishop Alduin, Nin's first bishop in the year 900, tasked with uncovering a forgotten pact.
Your mission begins at Donja Vrata, the main gate
Immerse yourself in Nin, Croatia's oldest royal city, and unravel the broken oath that sealed the fate of Dalmatian princes.
The story that haunts this land
Your journey into Nin's Croatian cultural heritage begins at Donja Vrata, the Lower Gate. This main entrance, dating from the 11th century, is built of local stone with a semicircular arch, typical of Dalmatian Romanesque architecture. It is an integral part of the medieval ramparts that protected Nin, Croatia's oldest royal city. It was here, under the centuries-old arches, that Croatian kings received envoys and where state secrets were sometimes sealed, or broken.
Continue towards Crkva Svetog Križa, the Church of the Holy Cross, a three-nave basilica measuring 8.2m long by 7.8m wide, built in the 9th century. Although often described as the smallest cathedral in the world, its historical importance is immense. It houses some of the oldest pre-Romanesque frescoes in the Slavic Balkans, silent witnesses to the beginnings of Christianity in Dalmatia. Designated a Croatian cultural monument in 1962, it represents a landmark in Nin's history.
The path then leads you to Rimski hram, the Roman Temple, remnants from the 1st century likely dedicated to Jupiter or Venus. This site, located on the ancient forum of Aenona, the former Roman capital of the region, reveals the foundations of a 20x18m podium with Corinthian columns. The presence of this temple highlights Nin's strategic importance during the Roman era, long before it became a Croatian royal city. This is where Roman legions and merchants came to honor their gods.
In the heart of Nin's historic royal quarter, the Spomenik knezu Branimiru, a monument erected in 1987, commemorates Prince Branimir. This Croatian ruler, reigning from 879 to 892, proclaimed Croatian independence in 879 through his 'Charter of Branimir'. His political audacity marked a turning point for the nation, with Nin serving as its first capital. The monument is a reminder of Branimir's commitment to Croatia's sovereignty, a powerful oath that still resonates through the streets of Nin.
Finally, your journey concludes on the Gradske zidine, the city walls. These medieval fortifications from the 11th-12th centuries, 1.1 km long and encompassing 8 ha, include 7 access gates like Donja Vrata and Gornja Vrata, equipped with watchtowers. They offer the best preserved example of a medieval Dalmatian city-state. By following these walls, you feel the weight of history, the protection they offered to the kings and bishops of Nin, and the central role of this city in the formation of Croatian heritage. This exploration of Nin's monuments leaves you with a deep understanding of its role as Croatia's oldest royal city and a site on the UNESCO tentative list.
