Your quest begins at Tvrđava Nehaj, the iconic fortress of Senj. Built between 1540 and 1550 by the Brothers of the Cross of Senj, the Uskoks, this imposing 52m x 52m and 20m high structure was erected to defend the Kvarner region against the Ottomans. From 1550 to 1616, it was the Uskok capital, housing 300 to 400 fighters. This is where the legends of the Uskoks took root before the fortress was destroyed in 1616 by the Venetians and Ottomans. Today, an ethnographic museum since 1959 exhibits Uskok artifacts and 16th-century weapons, immersing you directly in the history of Senj.
Descending towards the heart of the city, you reach Crkva Uznesenja Blažene Djevice Marije, Senj's main church. Built between 1100 and 1200 on a Roman site, it was rebuilt after the 1887 earthquake. This church is intimately linked to Ivan Lenković, Uskok captain from 1550 to 1567, where commemorative Uskok masses were celebrated. Its 40m high bell tower contains 14th-century Glagolitic inscriptions, testimonies to the rich Croatian Glagolitic heritage that permeates the history of Senj and the Kvarner region.
Your path then leads you to Trg Glagoljaša, Senj's central square. Named in honor of the city's Glagolitic tradition, this square recalls that Glagolitic missals were printed here as early as 1494, marking the publication of the first Croatian book. Here you discover Rački's statue (1876) and monuments dedicated to 16th-century Glagolitic bishops, often linked to the Uskoks. This place was the administrative center of Senj since the Middle Ages and the scene of Uskok assemblies in the 16th century, a crucial point in Senj's history.
Continue towards Luka Senj, the Port of Senj, a natural harbor used since Roman antiquity. This was a crucial Uskok naval base from 1550 to 1616 for anti-Ottoman raids. It was from here that Ivan Lenković led his documented naval operations between 1560 and 1565, making this port a strategic point in the Kvarner region. The quays, rebuilt in the 19th century, extend for 500m with a depth of 5-8m, and continue to bear witness to Senj's maritime importance.
The journey concludes by revealing Ulica Potok, a historic cobbled street connecting the old town to the port, lined with 16th-century houses featuring Uskok arches. This street, the main passage for the Uskoks to Nehaj fortress, retains remnants of medieval fortifications. Your exploration of Senj, a Croatian historical town, will have immersed you in Uskoci history and its Glagolitic heritage, from the ramparts of the Nehaj fortress museum to the port quays. You carry with you the memory of a city that, through centuries, has forged its identity and defended its freedom.
