Welcome to the Nature and Cultural Heritage Site Burgbichl
Dive into 4 billion years of Earth’s history and experience the harmony of unique nature and archaeological discovery. Burgbichl unveils a late-Antique hillside settlement (c. 400–600 AD) nestled within a landscape of remarkable beauty - featuring the juniper forest, the dramatic Kesselwände (rock formations), and the Upper Drau European Protected Area.
Upper Drau European Protected Area
North of Burgbichl stretches the 68-kilometer-long Upper Drau European Protected Area. It encompasses Austria’s largest inner-Alpine grey alder floodplain forest. The area is home to 19 fish species - including huchen and sculpin - and over 140 bird species, making it an ecological treasure. In recent decades, large parts have been revitalized and secured as habitats for rare species.
Juniper Forest and Kesselwandbach
The juniper forest is a dry floodplain woodland with a unique vegetation mix: red pines, tree-form junipers, and orchids such as lady’s slipper and spotted orchid. Rare butterflies like the Duke of Burgundy find a home here. The Kesselwandbach, a chalk-alpine mountain stream, also supports strictly protected pioneer plant species.
Historical Development of the Nature and Cultural Heritage
The Kesselwände – 4 Billion Years of Earth’s History
The Kesselwände tell the story of Earth’s formation:
4.57 billion years ago: Formation of our planet.
570 million years ago: Formation of the ancient bedrock of the Kreuzeck Group.
200 million years ago: Creation of dolomites, limestones, and marls in the Meliata Ocean.
Shaped by glaciers and erosion, Burgbichl and the Kesselwände achieved their present form.
These bizarre rock formations, with their reddish-brown hues, are a natural monument of exceptional beauty.
The Late-Antique Settlement
At Burgbichl stood a fortified hillside settlement between 400 and 600 AD.
Built for protection during the turbulent Migration Period.
Strategically located at the crossroads of major routes: Drau Valley – Gailberg Pass – connections to Italy and the Alps.
Accessed through a northern gate and forecourt.
Housing and workshops arranged on terraces, frequently constructed from timber on stone foundations.
Craft activities included iron and non-ferrous metal smithing, as well as bone carving.
Agriculture took place in valley fields, with some livestock kept within the settlement itself.
Water Supply
A central challenge of the hillside settlement was the lack of a natural spring. The solution: a large cistern situated near the upper church.
Dimensions: 6.4 × 3.9 meters; depth: 2.8 meters → capacity approx. 70,000 liters.
Lined with waterproof opus signinum (a Roman waterproofing plaster).
Frequently renovated and polish-finished in red for hygiene.
Archaeological finds within the cistern - coins, fibulae, and pottery fragments - indicate trade links reaching as far as North Africa and the Aegean.
The Upper Church
Atop the Burgbichl, in the early 5th century, a Early Christian church was erected.
Cruciform floor plan with a semicircular apse facing east.
Interior included a presbytery for clergy and a vestibule for catechumens.
Decor featured marble, riven floors, and reused spolia.
The church remained in use until the settlement’s abandonment at the end of the 6th century.
Graves were located around the church, including a founder’s grave adjacent to the apse.
The Lower Church
A second large church (22 x 18 m) was built near the eastern enclosure wall.
Features: screed floors, stained glass windows, priest's bench (cathedra)
Conversion: Reliquary chapel with altar, marble reliquary and ivory box
Side chapel with foot washing basin, later used as a baptistery
Reference to the veneration of martyrs and relics
Significance of the Ostrogoths (493–536 AD), who had their own Arian church organisation

Irschen, village of nature and herbs
The herb village of Irschen, with around 2,000 inhabitants, is located on a sunny terrace 800 metres above sea level.
Sunny, mild climate – ideal conditions for herb cultivation and agriculture.
Known throughout Europe as the ‘herb village’ since the 1990s and recipient of multiple awards.
Sights: late Gothic churches, herb house, show gardens, waterfall, mills and alpine pastures.
History: first finds from the Neolithic Age (2600 BC), Bronze Age spearheads, later settlement by Romans around 300 AD, Slavs from 610 AD, Bavarians from 743 AD
