The fort was constructed using local limestone extracted directly from the island of Ugljan.
During the Venetian era, the fortress served as a critical strategic point to monitor maritime traffic entering the Zadar channel.
The site features a distinctive radio/telecommunications mast integrated into the historical perimeter.
Archaeological surveys have confirmed that the fortress was built directly over prehistoric Illyrian burial mounds.
The structure provided a tactical signal relay link between the mainland and Venetian maritime outposts.
Tvrđava Sveti Mihovil is a medieval stone fortress located atop the highest peak of Ugljan Island at 265 meters above sea level. Its foundations date back to a 6th-century Byzantine watchtower, though the current structure was primarily shaped by the Venetians in the 13th century. The site offers a 360-degree vantage point over the Zadar archipelago and the Kornati National Park. The limestone walls remain partially intact, demonstrating typical medieval defensive military architecture. The site is accessible via an asphalt road suitable for cars and bicycles. It functions as an unstaffed open-air historical observation point.

Wear sturdy, closed-toe hiking or athletic shoes due to the uneven and loose rocky terrain within the fort.
Bring your own water and sun protection, as there are no amenities, shade, or facilities at the summit.
Check wind speeds before ascending, as the hilltop is completely exposed and can experience high gusts.
Do not attempt the ascent during thunderstorms due to the high probability of lightning strikes at the summit.
Open year-round; however, the access road may be temporarily blocked by snow or storm debris in winter.
Respect the ruins by not climbing on or removing stones from the perimeter walls; carry out all trash.
