Grmozur

The prison island on the skadarsko jezero.

Hidden in the wide, reed-fringed waters of Skadarsko jezero, near the village of Godinje (Bar Municipality), the small island of Grmožur feels like a story left behind—stone walls rising from still water, silence broken only by wind and birds.

Once a military outpost, later a feared prison, and today a ruin reclaimed by nature, Grmožur is often called the “Montenegrin Alcatraz”—a nickname that hints at both its isolation and its legends.

🏰 A fortress in miniature

Grmožur’s fortification was built in the 1840s. Despite its small size—about 430 m²—the complex was designed for control: an irregular footprint adapted to the rock, with two entrances and defensive positions that watched over the lake. On the western side, a guard tower once dominated the fortress, reinforcing the feeling that this island was built to observe and contain.

🔒 From fortification to prison

During the time of Prince Nikola Petrović, the structure was converted into a prison—first for serious offenders, and later increasingly for political prisoners. The island’s isolation made it an ideal place for confinement. Local stories say the prison was considered almost impossible to escape from: many prisoners were believed to be non-swimmers, and patrol boats regularly circled the island to prevent any attempt to reach the shore. This is how Grmožur earned its famous nickname: the “Montenegrin Alcatraz.”

🌿 Ruins, birds, and the feeling of a forgotten place

A strong earthquake in the early 20th century caused significant damage to Grmožur’s fortress. It was never fully restored, and today the island remains a haunting ruin—broken walls, open sky where roofs once stood, and nature slowly taking back the stone.

🐦 Nature Reclaims the Walls

Locals have nicknamed the islet “Snake Island,” while ornithologists often call it an “Island of Birds,” as it’s known as a nesting site — a reminder that Skadar’s wildlife continues to thrive even around places shaped by human history.

What makes Grmožur especially fascinating is the contrast between its heavy past and its peaceful present. The ruins are now surrounded by the calm waters of Skadarsko jezero and inhabited by many bird species, turning the island into a place where history and wildlife quietly coexist.

🚤 How to experience Grmožur

  • Best way to see it: by boat tour on Skadarsko jezero, often departing from Virpazar or nearby lakeside points.
  • Go for atmosphere: early morning or golden hour for softer light and calmer water.
  • Respect nature and safety: the ruins can be unstable, and wildlife may be present—many visitors prefer to admire the island from the boat rather than landing.

🌟 Tip: Combine your visit with Godinje and the lakeside villages nearby for a full day of history, nature, and authentic local atmosphere.
