St. Michael’s Fortress on Ugljan Island: A Hidden Gem in the Zadar Archipelago

Nestled on the northwest hill of Ugljan Island, just a stone’s throw away from Zadar, lies the captivating St. Michael’s Fortress (Tvrđava sv. Mihovila). This historical gem, though not as famous as some of Croatia’s more celebrated islands, is a true paradise for those seeking unspoiled beauty and rich history.
A Glimpse into History
The history of St. Michael’s Fortress dates back to the late 11th or early 12th century when it was associated with the Benedictine Monastery of St. Michael. Originally, it served as a branch of the Benedictine Monastery of St. Krševan in Zadar, but over time, it gained autonomy and the Dominicans took over the fortress in 1570. However, very little is known about its appearance, except for the design of the church of St. Michael, documented in the drawings by Franjo Salghetti.

The fortress, as we see it today, was constructed by the Venetians in 1202, following the conquest and destruction of Zadar. Its irregular trapezoidal shape mirrors the contours of the hill’s summit. On the southern side, almost flat curtain walls are reinforced with rectangular corner towers and a bastion on the northeast corner.
The grand keep tower near the northern gate was demolished in 1948, along with the remains of the medieval Church of St. Michael, located in the center of the courtyard.
Reaching St. Michael’s Fortress
The island of Ugljan is conveniently located just across from Zadar, accessible to anyone who books a speedboat trip with Zadar Archipelago, taking only 10 minutes to reach. Although it may not be as popular as some of its counterparts, the island boasts numerous attractions that will enchant you.
One of these attractions is undoubtedly St. Michael’s Hill (265 meters), atop which sits the aforementioned fortress. During your climb up the hill, you will be escorted by the local tour guides of Zadar Archipelago.
The fortress itself may not be particularly extraordinary in terms of architecture, but the real treasures here are the unspoiled nature and the breathtaking 360-degree panoramic views. From this vantage point, Zadar lies at your feet, and to the south and west, you’ll have views of numerous islands in the Zadar archipelago and even glimpses of the distant Kornati National Park.
A Natural Paradise
The natural beauty surrounding the fortress is truly remarkable. As you travel along the 3.5-kilometer road from the ferry port in Preko towards the summit of St. Michael’s Hill, you’ll be greeted by olive groves that gradually give way to wild vegetation and pine trees.

The rocky terrain showcases the “krš” landscape at its finest, giving way to amusing stone formations, incredibly-aromatic plants and grazing goats and donkeys. Many opt to hike or bike to St. Michael’s Hill, but there is also a well-maintained road leading to a spacious parking area at its peak.
Exploring the Fortress and Beyond
St. Michael’s Fort has seen better days, and recent archaeological work has paved the way for restoration efforts.
To make your visit even more exciting, consider exploring the hiking trails around the fortress. On this occasion, you can venture towards the northwest to visit the Pećina (Cave). This small speleological marvel is the first cave in Croatia about which there are written records, with Benedictine monks from the aforementioned monastery being the ones who wrote about it.
The path to the cave is not challenging; most of the trail follows rocky blocks that have been shaped by natural forces over thousands of years. The coastal views are hypnotic, and the time seems to fly by as you make your way to the cave, which is visible in the distance from the fortress. The Željina Cove, just below, beckons for a swim, but the steep descent may be a challenge too great for older guests.

Approaching the cave, the landscape becomes even more incredible. At this part of the journey, you’ll lose another half hour admiring the views and exploring various stone formations. Here, the feeling of wilderness is heightened by the silence, occasionally interrupted by the calls of birds of prey that nest in the area. The descent to the cave requires some extra care, but the trail remains suitable for children and “pensioners” alike.
If you have extra time, consider taking a right turn on your way back to explore the marked circular trail around St. Michael’s Hill, which passes under the Željina cliffs. The trail exits beneath the fortress parking area.
The story of this bay and the St. Micheal`s monastery may remind you of another hard-to-reach bay and monastery on another island, namely, the Blaca Desert on the island of Brač. Each of these locations is unique and extraordinary in its own way.
