SLOVENIA Late Antique settlements-refugees in Slovenia
Ajdna is one of the most important Late Antique archaeological sites in Slovenia, combining historical, cultural, and natural heritage in a strikingly picturesque mountain landscape.
Ajdna (1064 m) is a prominent rocky outcrop on the southern slope of Mt. Stol in the Karawanks, dramatically rising above the village of Potoki in the Municipality of Žirovnica. Its jagged silhouette, reminiscent of a stone fortress wall, stands out from afar and creates an impression of natural dominance over the Upper Sava Valley.
This is an exceptionally strategic location that served as a natural defensive stronghold in Late Antiquity. The steep cliffs of Ajdna are nearly impassable from all sides, offering the settlement a high degree of protection against invasions. The only access to the summit is via a narrow ridge from the west, now part of a hiking trail. Archaeological research and field analysis suggest that this ridge was likely artificially narrowed-either by excavation or reinforcement-to further hinder access and enhance the settlement’s defensive function.
Just west of Ajdna lies Mala Ajdna, a lower rocky elevation forming a natural forepart of the main ridge. Though less prominent, Mala Ajdna complements the dramatic geological backdrop and adds to the terrain’s complexity. Its position offers an additional vantage point and may have served as an early warning post or auxiliary defensive station in the past.
From the summit of Ajdna, a panoramic view unfolds: to the south lies the Upper Sava Valley with Jesenice, the Bled Basin, and the Mežakla Plateau; to the west, the view opens to the Julian Alps with Slovenia’s highest peaks. This visual dominance was crucial for monitoring traffic routes and early detection of threats.
Geologically, Ajdna is part of a limestone ridge formed in the Mesozoic era and subject to intense weathering. Vegetation is adapted to the steep terrain: rare alpine plants thrive on rocky ledges, while beech and spruce forests cover the lower slopes. This blend of natural ruggedness, biodiversity, and historical strategic value makes Ajdna one of the most fascinating natural-cultural landmarks in Slovenia’s alpine region.
Ajdna belongs to the limestone ridge along the southern edge of the Karawanks. These sedimentary rocks, formed in the Mesozoic, have been uplifted and fractured into dramatic shapes by tectonic forces. Vertical walls, cracks, and natural ledges create an almost impenetrable natural barrier. This geological configuration was exploited in Late Antiquity as natural defensive architecture, allowing minimal construction for maximum security.
The accessible ridge from the west is Ajdna’s only natural weak point. Its narrowness and exposure suggest it was likely artificially modified-through excavation, reinforcement, or even wooden barricades-to serve as a controlled entry point. This defensive logic is comparable to other alpine hilltop settlements such as Tonovcov grad above Kobarid or Rifnik near Šentjur, where natural features were complemented with minimal fortifications.
Ajdna ranks among the most significant Late Antiquity hilltop settlements in Slovenia. During the collapse of the Western Roman Empire (5th–6th century), people fled from the lowlands to escape barbarian invasions-mainly by the Lombards and Avars-and sought refuge in hard-to-reach locations. These hilltop settlements were temporary sanctuaries, often with religious structures, reflecting the importance of spiritual protection.
Compared to other such settlements, Ajdna stands out for its:
• exceptional natural protection (steep cliffs, narrow ridge),
• panoramic control over the valley (observational function),
• archaeological preservation (church, graves, houses),
• mythological connection (Ajdna Maiden as a cultural icon).
While some hilltop refuges later evolved into permanent settlements or castles, Ajdna was not continuously inhabited after the early Middle Ages, indicating its temporary function-as a defensive and spiritual refuge during times of crisis.
The settlement at Ajdna emerged in Late Antiquity, likely in the second half of the 5th century, during the decline of the Roman Empire, when provincial authority receded and lowland security became increasingly uncertain. In response to invasions-primarily by the Huns, Lombards, and later Avars-inhabitants retreated to inaccessible hilltops, where they could monitor the valley and defend against raiding expeditions.
Archaeological findings show the settlement was densely built with several dozen houses made of local stone. Among the discoveries:
• remains of dwellings with hearths,
• pottery, tools, and coins,
• food remnants indicating basic self-sufficiency,
• a church with an apse, confirming a Christian community,
• graves, including that of a young woman with jewelry, now a central symbol of Ajdna.
Life at Ajdna was modest but organized. Inhabitants engaged in agriculture, livestock farming, foraging, and possibly crafts. The church at the edge of the ridge suggests a spiritual center for a community seeking protection through faith during uncertain times.
Life at Ajdna was adapted to the harsh conditions of a rocky hilltop settlement: water was sourced from nearby springs, agriculture took place on terraces below the ridge, and graves reflect spiritual organization and social stratification. Ajdna was part of a broader network of Late Antique hilltop settlements in the Alpine region.
There is no permanent water source at Ajdna’s summit, a major challenge for a hilltop settlement. Inhabitants likely obtained water from springs on lower slopes, especially to the southwest where terrain is more accessible. They may have used rainwater collectors or carried water in vessels from the valley. Archaeological evidence shows no large water structures, confirming the settlement’s temporary and crisis-adapted nature.
Ajdna is rocky and steep, but the settlement spread across several terraces west and south of the summit, where basic agriculture was possible. On these natural or artificially shaped flats, residents cultivated grains, legumes, and vegetables suited to mountain conditions. They also raised livestock, mainly small ruminants grazing on steep meadows. Food remains confirm the community’s self-sufficient orientation, essential for survival in isolation.
Several graves were discovered within and around the church, indicating organized burial practices. The most famous is the grave of a young woman with jewelry, buried with great care, suggesting special status-perhaps spiritual or social. The presence of graves in the church indicates a Christian community seeking spiritual protection during uncertain times. The graves were oriented and structured, confirming the influence of church norms and rituals.
Ajdna was not isolated-it was part of a wider network of Late Antiquity hilltop settlements across the Alpine region. Over 50 such sites are known in Slovenia, including Rifnik, Tonovcov grad, Vranje, and Gradišče above Bašelj. These settlements were temporally and functionally connected: serving as refuges, observation posts, and religious centers. They may have been linked by mountain paths enabling communication and information exchange.
Ajdna was thus a vibrant but crisis-driven community that established basic infrastructure for survival, spiritual life, and defense. Its connection to other settlements reflects regional responsiveness to the empire’s collapse and foreign invasions.
Ajdna was not a permanent settlement. Archaeological traces indicate a sudden and violent end:
• signs of fire in several buildings,
• unburied remains,
• cessation of church use.
It is believed the settlement was destroyed in a single attack, likely in the early 6th century, when Avars and Lombards moved through the Alpine region. Ajdna’s defenders were evidently poorly armed or too few to resist an organized assault. After its destruction, the settlement was never rebuilt.
The church at Ajdna is the highest-located Late Roman church in Slovenia and a central symbol of the spiritual life of the Late Antiquity community that sought refuge on this rocky outcrop.
The church stands at the extreme southeastern edge of Ajdna, right beside a precipitous cliff, giving it a dramatic and symbolic position—as if guarding the settlement from the outside world. It was built in the 5th or early 6th century, when Christianity was firmly rooted in the daily life of Roman provincial inhabitants.
The church was a single-nave structure with a semicircular apse on the east and a vestibule (narthex) on the west. It was built from local limestone using mortar, indicating good knowledge of construction techniques of the time. Its floor plan measures approximately 6 × 4 meters, reflecting the modest conditions of a hilltop settlement.
Inside and near the church, archaeologists discovered several graves, confirming its role as a burial chapel. The most famous is the grave of a young woman buried with rich jewelry, now the central symbol of Ajdna and linked to the legend of the Ajdna Maiden. The presence of graves in the church suggests special status of the buried—perhaps priests, community leaders, or members of prominent families.
The church was likely the center of the community’s liturgical life: a place for prayer, rituals, baptisms, and burials. Its location on the edge of the ridge carries symbolic weight—as a threshold between earthly and heavenly, between the safety of the settlement and the danger of the outside world.
The church was destroyed by fire along with the rest of the settlement, which archaeologists associate with a violent incursion in the early 6th century. It was never rebuilt. Today, the church’s foundations are visible, conserved and presented to visitors. An information board beside the church shows its floor plan and interpretation of the finds.
Ajdna’s church remains the highest-located Late Roman church in Slovenia, giving it exceptional significance in the history of Christianity in the region. It is also a rare witness to spiritual life during the empire’s collapse, when people sought refuge not only in natural fortresses but also in faith.
Key Differences:
The church at Ajdna is therefore exceptional in its isolation, elevation, and connection to refuge, while other Late Roman churches reflect the development of institutional Christianity in more accessible and stable environments.
