Construction is projected to take approximately 40 years to complete based on traditional methods.
Only hand tools such as chisels, saws, and wooden cranes are permitted on the construction site.
The project functions as a scientific experiment to understand the logistics and energy requirements of medieval fortress building.
Local granite and limestone are sourced and processed on-site by stone masons.
The mortar is produced on-site by burning limestone in a traditional kiln to recreate authentic binding materials.
The castle is being built without the use of blueprints, relying instead on empirical medieval architectural knowledge.
Horses are utilized as the primary means of transport for heavy materials within the site boundaries.
The construction crew includes international master craftsmen who teach apprentices the nearly forgotten techniques of medieval building.
The Castle Building Experience in Friesach is an ongoing, long-term construction project utilizing only medieval tools and techniques to build a full-scale stone castle. Initiated in 2009, the site serves as both an architectural experiment and an educational center for historical stonemasonry and timber-framing. No modern machinery, electricity, or engines are used in the construction process. Workers rely on historical models, such as pulleys and ramps, to transport heavy granite and limestone. The project is designed to last several decades, allowing visitors to observe layers of the construction process across different seasons. The site includes a smithy, a lime kiln, and animal paddocks to support the daily lives of the craftspeople. It occupies a site on the outskirts of Friesach, the oldest town in the Austrian state of Carinthia. The final goal is to erect a complete 12th-century style fortress according to period-accurate structural principles.

Wear sturdy, closed-toe footwear as the site is an active construction zone with uneven, dirt-packed paths.
Check the official website for daily demonstration schedules before arriving to time your visit with active stoneworking sessions.
Bring a hat and sunscreen, as there is limited shade in the open-air construction yard.
Do not attempt to touch tools or building materials left out, as these are often in active use or represent historical research items.
Open seasonally from spring through late autumn; closed during winter months.
Maintain a safe distance from active construction areas and observe all warning signs around cranes and heavy lifting equipment.
