Your journey in Senj begins at the foot of Tvrđava Nehaj, a fortress built in 1558 by the Uskok Knights to defend the city against the Ottomans. This main tower, 25 meters high with its 217 steps, was the heart of the anti-Ottoman pirates' operations until 1616. From its battlements, Uskoks like Vuk Mandušić watched the sea and the Kvarner islands, ready to launch their raids. You will discover the defense strategies and ingenuity of these warriors who marked Croatian history.
Descending from the fort, you walk along the Gradski bedemi, the Venetian ramparts reinforced between 1553 and 1558, which protected the port of Senj. These walls, with a total length of 1.2 km and 12 surviving bastions, were crucial for the rapid communication of Uskok messengers to the islands. Part of these remains are now integrated into the modern buildings of the historic center, offering a striking contrast between the defensive past and urban life. Your itinerary then leads you to Katedrala Uznesenja Blaženoga Djevica Marija, the main church of Senj. Rebuilt after the 1886 earthquake, it stands on the foundations of a 5th-century basilica. Its 40-meter bell tower, completed in 1750, has witnessed centuries of history, from Glagolitic rites to 18th-century Baroque frescoes.
Your route through Senj then takes you to Ulica Vodnikova, a 16th-century cobbled street, lined with 17th-18th century stone houses. This main thoroughfare, 500 meters long, was essential for messengers between Nehaj Fort and the port. You will see Glagolitic inscriptions dated 1527 on the facades, a testament to Croatia's rich Glagolitic heritage. Further on, Trg glagoljaša, the central square, pays tribute to this unique alphabet. Senj was a major center of Glagolitism from the 14th to 16th centuries, with the printing of liturgical books, and the statue of the Glagolitic bishop Ivan Mažuranić, erected in 1898, is living proof of this.
Continue your visit to Senj towards Crkva sv. Franje, a Franciscan church built in 1680, adjacent to a monastery founded in 1230. Its library houses over 400 15th-century Glagolitic manuscripts, a treasure for Croatian Glagolitic heritage. The 32-meter Baroque bell tower, added in 1760, dominates the district. This place was also a refuge for Uskoks during Ottoman sieges in the 16th century, offering insight into their daily and spiritual life. Then, Luka Senj, a historic natural port, was the Uskok naval base for their raids against Ottoman fleets. Active since Roman antiquity as the port of Aquilonium, it directly connected Nehaj Fort via a 300-meter path, facilitating troop and goods movements.
Your Uskok messenger quest ends at Trg Čilnica, formerly the bell square, 400 meters from Nehaj Fort. This site, with its 14th-century medieval bell tower for alarm signals, was a place for weekly markets since 1449, thanks to a charter from Queen Elisabeth. It is here, in the heart of the Glagolitic artisans' quarter, that you deliver your final message. This thematic circuit in historic Kvarner will have allowed you to understand the strategic role of Senj, a true Uskok Fortress UNESCO candidate, and to walk in the footsteps of Croatia's defenders, exploring the rich Glagolitic heritage and Croatian historical monuments of this coastal city.
