St. Sylvester's Church Biševo – Benedictine Heritage from the 11th Century

St. Sylvester's Church on Biševo is the most significant religious monument on the island and one of the places that best illustrates how much older and richer Biševo's history is compared to its current tourist narrative surrounding the Blue Cave.

It is located in the settlement of Poje, on a plateau in the island's interior, among old stone houses and former fields. At first glance, it appears to be a simple small island church, but behind it lies nearly a thousand years of documented history.

The current church dates back to the Middle Ages, with its story beginning in 1050, when the priest Ivan Gaudijev Grlić from Split built a church dedicated to Pope St. Sylvester and entrusted it to the Benedictines from the Italian Tremiti Islands. Soon after, a Benedictine monastery was established nearby, integrating Biševo into an important network of monastic communities across the Adriatic.

The Church Built in 1050

The year 1050 is a key date in Biševo's history.

At that time, the priest Ivan from Split constructed a church on the central plateau of the island and dedicated it to St. Sylvester I., a pope from the 4th century.

The church was then handed over to the Benedictines from the Tremiti Islands, who expanded their network of monasteries across the Adriatic.

This strategic location of Biševo was not coincidental. The island lies on a maritime route between the western and eastern coasts of the Adriatic, making connections with southern Italy much more intense in the Middle Ages than one might assume today by looking at a map.

The Benedictines built the St. Sylvester Monastery, and the entire area became one of the more significant spiritual and economic centres of this part of the Adriatic.

Benedictines from Tremiti

The Benedictines who arrived on Biševo were part of a broader Adriatic network connected to the Tremiti Islands in Italy.

At that time, the sea did not represent a boundary as we often imagine it today. On the contrary – it was the quickest route between the shores.

Biševo, Svetac, Vis, Hvar, Tremiti, and the Gargano area were linked by maritime routes frequented by monks, traders, and sailors.

Thus, the St. Sylvester Monastery was not an isolated monastery at the edge of the world, but part of a much broader cultural and religious landscape.

Traces of this Benedictine influence later appeared on Vis, particularly in the Komiža area.

Pope Alexander III Protected the Monastery

The significance of the Biševo monastery is highlighted by a document from 1181.

During the conflict between Venice and Byzantium for dominance over the Adriatic, the monastery sought protection from Pope Alexander III.

On 2 May 1181, the pope issued a privilege placing the St. Sylvester Monastery and its community under his protection.

The document directly addresses the abbot Ursus, the head of the Biševo monastery.

This is particularly valuable information as it confirms that in the 12th century, there was not just a small church here but an organised and sufficiently significant Benedictine community that communicated directly with the papal administration.

Only the Church Remains of the Monastery Today

The Benedictine complex has not survived in the form it existed during the Middle Ages.

Today, St. Sylvester's Church is the main preserved part of the former monastery, while it is assumed that the monastic buildings were located immediately adjacent to it, particularly on the southern side.

Inside the church, doors that once led to the monastic courtyard have also been uncovered.

The surrounding stone houses, walls, and gardens have altered the original appearance of the space over the centuries, so today's visitor stands on a very layered archaeological site, parts of which have yet to be fully explored.

An Even Older Church Found Beneath

One of the greatest surprises came during conservation and archaeological research in the 1990s.

It was revealed that the church from 1050 was not built on completely vacant land.

Underneath the current structure, remains of an older early Christian church, likely from the 6th century, were discovered, including an apse and part of a mosaic floor.

This indicates that this site had a sacred function several centuries before the arrival of the Benedictines.

Other ancient and late antique traces, including pottery and a fragment of a Greek tombstone bearing the name Theodoros, were also found in the church area.

Thus, St. Sylvester's Church is not merely a medieval monument. It is situated on a site that can trace a very long continuity of life and use.

The Current Appearance Differs from 1050

The church was originally built in a pre-Romanesque style, but has been repaired and reshaped multiple times over nearly a thousand years.

Official sources particularly note changes in the 17th and 20th centuries, while other construction works occurred even earlier.

Therefore, the current exterior is the result of several different historical layers.

The single-nave stone structure has a simple façade and a bell tower, while strong stone buttresses can be seen along the side walls.

Inside, details from various phases of construction can still be recognised today.

The church is not large, but its simplicity and isolated location give it a strong character.

A Unique Narrow Window Above the Apse

One of the more interesting details is located on the eastern wall above the apse.

There is a very narrow and tall window, almost resembling a loophole from the outside, which widens towards the interior.

During earlier renovations, it had been bricked up, but restorers have reopened it.

In the morning, a narrow and strong beam of sunlight enters through it into the darker interior of the church.

It cannot be definitively stated that the entire effect was intentionally designed this way from the beginning, but today it is one of the most intriguing details of the church's interior.

The Biševo Madonna – One of the Greatest Artistic Treasures Associated with the Church

St. Sylvester's Church is also linked to a highly valuable medieval artwork – the Biševo Madonna.

This depiction of the Virgin Mary with Child dates from around 1220 and is one of the oldest preserved representations of the Virgin Mary of its kind in Dalmatia.

The painting was once housed in St. Sylvester's Church on Biševo.

Today, it is no longer on the island, but is kept in the Cathedral of St. Stephen in Hvar.

Therefore, visitors entering the church today will not see the original Biševo Madonna, but it is important to know that one of the more valuable works of medieval Dalmatian art originated from this small island church.

Benedictine Graves Beneath the Floor

Archaeological research has also uncovered several graves within the church.

Along the northern and southern walls, communal graves containing multiple individuals have been found, believed to belong to Benedictine monks.

Particularly interesting is a grave located almost at the central axis of the church, in a privileged position in front of the apse.

Archaeologists have speculated that a person of great importance to the monastery must have been buried there. One possibility is that it could be the priest Ivan who commissioned the church's construction, but this has not been proven and should be regarded as an intriguing archaeological hypothesis rather than a certainty.

How to Reach St. Sylvester's Church?

The church is located in Poje, in the central part of Biševo, far from the coast and main ports.

To reach Biševo, one must first take a boat from Komiža, and then continue on foot along island paths towards the church.

The church is one of the official stops on the Geostaze Biševo, making it a pleasant addition to a longer tour of the island's interior.

It is most practical to combine it with the Visitor Centre for the Blue Cave – Biševo, the settlement of Poje, and onward to Porat or Salbunari.

Good walking shoes or sturdy sandals are recommended. In summer, it is advisable to carry enough water as a large part of the path is exposed to the sun.

Is It Worth Visiting If Only Touring the Blue Cave?

If the plan is to spend only a very short time on Biševo and return to Komiža immediately after visiting the Blue Cave, the church is difficult to fit into such a schedule.

However, if one stays on the island for half a day or a full day, it is certainly worth including.

The Blue Cave showcases the natural side of Biševo, while St. Sylvester's Church reveals its historical aspect.

Moreover, after visiting the church, it becomes much easier to understand why this small island has held much greater significance for centuries than one might conclude from its current population.

Can the Interior Be Visited?

The church is not arranged like a typical museum with a ticket office and fixed tourist hours.

Therefore, one should not assume that the interior will always be open upon a self-guided visit.

Even when the doors are closed, it is worthwhile to come for the building itself, the historical surroundings of Poje, and the remnants of the former monastery.

If an interior visit is particularly important, it is best to check access possibilities before arriving on the island or through the local tourist/visitor system on Biševo.

The Most Important Historical Building on Biševo

Today, the Blue Cave is incomparably more famous, but in historical terms, St. Sylvester's Church is one of the most important buildings on the entire island.

At this site, one can trace ancient and early Christian traces, the 11th-century church, the arrival of the Benedictines from Tremiti, the development of the monastery, the papal privilege from 1181, and the Biševo Madonna from the 13th century.

All of this is found in a small stone church in the midst of a quiet island settlement that most quick day-trippers never reach.

If one wishes to explore Biševo beyond the Blue Cave and sandy beaches, St. Sylvester's Church is one of the locations that should not be missed.
