Ostrog Monastery is the most astonishing sight in Montenegro's interior: a group of white churches literally set into a sheer wall of rock, almost 900 metres up, as if they grew out of the mountain itself. It is Montenegro's largest pilgrimage site and one of the most important in the Balkans and the whole Orthodox world, visited every year by Orthodox, Catholic and also Muslim believers who come to pray for health and miracles.
The shrine holds the relics of Saint Basil of Ostrog (Sveti Vasilije Ostroški), the 17th-century bishop whose body, according to the pilgrims' faith, remains incorrupt and works healings. Long queues of the faithful form in front of his reliquary, in a cave chapel carved into the rock. The sight of the Upper Monastery clinging to the cliff, with clouds fraying over the Bjelopavlići valley, is one of the most striking postcards in the country.
This guide explains how to visit respectfully and without stress: the difference between the Lower and Upper monasteries, how to get up there (by car, on foot, or by train and trail), opening hours and queues, the dress code and the best times to avoid the crowds. A sacred, awe-inspiring place, whatever your own beliefs.
Ostrog was founded in the 17th century by Vasilije (Basil), Metropolitan of Herzegovina, who withdrew to these rocks fleeing Ottoman pressure and built the cave churches. After his death in 1671 he was canonised, and his relics, venerated as miraculous, turned the site into a major pilgrimage centre that has survived fires, wars and centuries of Balkan history. The upper church preserves frescoes painted directly onto the rock. The full story is on our history page.

Origins, formation and what the sources say.
The story of Ostrog is the story of a man who turned a rock face into a sanctuary. In the early 17th century, the Orthodox Balkans lived under Ottoman rule, and being a Christian bishop meant leading under constant threat. Into that world, around 1610, Stojan Jovanović was born in the village of Mrkonjići, in the Herzegovinian region of Popovo Polje. He came from a devout peasant family, entered a monastery as a young man, took the name Vasilije (Basil) and rose through the church hierarchy until he was consecrated Metropolitan (bishop) of Herzegovina.
Vasilije was a tireless pastor in extremely hard times. He travelled his diocese encouraging the faithful to keep their faith, rebuilding ruined churches and defending his people against abuses by Ottoman lords, as well as against pressure from the Catholic Church and from converts to Islam. That work earned him powerful enemies. The pressure on him and on his seat at Tvrdoš, near Trebinje, became unbearable, and in the mid-17th century the bishop had to seek refuge further inland, in the mountains of the Bjelopavlići country, in what is now Montenegro.
There, on the Ostroška Greda massif above the fertile Bjelopavlići valley, Vasilije found some caves in an almost vertical cliff of white rock. Small communities of hermits already lived in the area. The bishop decided to settle in that eagle's nest, inaccessible and protected by the mountain itself, and to turn the caves into churches. It was the founding act of Ostrog: faith literally seeking the heights in order to survive.
With patience and unshakeable faith, Vasilije and his monks fitted out the caves in the cliff. In one of them they consecrated the Church of the Presentation of the Virgin (Vovedenje), and on a higher level, using another cave, the Church of the Holy Cross (Krsta Časnog). Around 1667 the latter was decorated by the master painter Radul with frescoes painted directly onto the cave's natural rock, following its curves and irregularities: a unique work of religious art that has survived for centuries, sheltered by the overhang of the mountain.
Building a monastery in such a spot was an almost daily miracle: materials, water and supplies had to be carried up along impossible paths, and community life went on suspended over the precipice. But that very difficulty was its strength. Ostrog proved impregnable to the Ottomans, who controlled the plains but could not take that stronghold hanging in the rock. The monastery became a symbol of spiritual resistance: while mosques multiplied in the valleys, high on the cliff the lamp of the Orthodox faith kept burning.
Vasilije spent his last years at Ostrog, devoted to prayer, penance and the care of his community. He died on 29 April 1671 (according to the calendar of the time) in his mountain cell. He was buried in the monastery itself. No one could have imagined then that the tomb of a persecuted bishop would become one of the greatest pilgrimage sites in south-eastern Europe, or that the name of Ostrog would come to resonate among believers of three religions.
According to the monastery's tradition, seven years after his death, in 1678, Vasilije appeared in a dream to a monk of the Monastery of St Luke in Župa and asked for his tomb to be opened. When it was, they found his body incorrupt, intact and smelling of basil, a sign the Orthodox Church interprets as proof of sainthood. Vasilije was canonised as St Basil of Ostrog (Sveti Vasilije Ostroški), and his relics, placed in the cave church of the Presentation, began to draw believers who credited him with healings and miraculous intercessions.
Over the centuries, St Basil's fame kept growing. Ostrog became the largest pilgrimage centre in Montenegro and one of the most important in the entire Orthodox world, comparable in devotion to the great Balkan shrines. What is remarkable is its ecumenical character: not only Orthodox believers make the climb, but also Catholics and even Muslims, who venerate the saint and ask him for health and protection. Few religious figures in the Balkans enjoy such cross-community devotion, able to bring together communities often set against each other by history.
Pilgrims walk up from the Lower Monastery to the Upper one along a steep path, many barefoot as an act of penance, and queue for hours to venerate the saint's reliquary in the half-light of the cave chapel. The feast of St Basil, on 12 May (Julian calendar: 29 April), draws huge crowds. Over generations, countless accounts of healings attributed to his intercession have been gathered, cementing Ostrog's reputation as a place of miracles.
Ostrog's history has not only been one of miracles and pilgrimages: it is also one of disasters overcome. The monastery has suffered fires and damage over the centuries. The worst came in 1923, when a great fire devastated much of the Upper Monastery complex. Yet, and this further strengthened its sacred aura among believers, the relics of St Basil and the oldest cave churches, including the frescoes on the rock, were spared by the flames. The rebuilding that followed restored the monastery's appearance, with the distinctive white façades set into the cliff that we know today.
During the Second World War, in a country occupied and torn apart by partisan war and civil war, Ostrog once again became a refuge and a symbol. Its location and its meaning kept it a spiritual point of reference in violent times. In officially atheist post-war socialist Yugoslavia, many religious shrines lost their public importance, but popular devotion to St Basil never faded: pilgrims kept climbing the mountain, in a cult that withstood political change just as it had once withstood the Ottomans.
The Lower Monastery (Donji manastir), with its 19th-century Church of the Holy Trinity and free accommodation for pilgrims, grew into the gateway and welcome centre, while the Upper Monastery (Gornji manastir) remained the sacred heart. Between the two, the pilgrimage path kept alive the tradition of walking up to the relics, a practice that links today's pilgrim with centuries of faith.
In present-day Montenegro, independent since 2006, Ostrog combines its role as a living shrine with that of a major tourist attraction. Every year, hundreds of thousands of people climb the mountain: pilgrims who come to pray before St Basil and travellers from all over the world drawn by one of the country's most astonishing sights, the white churches merging with the cliff at almost 900 metres above sea level. Admission and parking are free, and the monastery keeps up its traditional hospitality, with accommodation for pilgrims and water for walkers.
That dual role also brings challenges. In high season, especially on summer Saturdays, the flood of coaches and cars clogs the winding road, and queues to venerate the relics can last for hours, straining the balance between the sacred side of the place and tourist pressure. The monks and the authorities try to preserve the shrine's atmosphere of contemplation, reminding visitors of the rules of respect: silence, appropriate clothing and behaviour fitting for a place of worship.
Whatever your own beliefs, Ostrog leaves an impression on everyone. It embodies something deep in Montenegrin and Balkan history: a people's ability to hold on to its identity in the harshest conditions, finding a space of spiritual freedom even in a vertical rock face. The figure of St Basil, venerated by Orthodox Christians, Catholics and Muslims alike, also makes it a rare meeting point in a region marked by division. Climbing to Ostrog, watching the Bjelopavlići valley open out below you and feeling the fervour of the pilgrims in the half-light of the cave is a glimpse into the very soul of Montenegro.
