The interior has been adapted for use as a small conference center and includes both dormroom accommodation and a separate guest house for couples or families. The almost idyllic setting of Alpine lakes and mountains makes a great venue for spiritual retreat or study.


Schloss Heroldeck is situated on wooded northern slopes overlooking the Millstattersee. With the entrance driveway leading off the B98 just east of the village Millstatt, the property is less than 8 kilometres from the A10 autobahn linking Salzburg and Villach.


To the front of the main building there is a south facing lawn and patio with open views across the lake. A variety of woodland paths onto the surrounding hills link directly to the Austrian footpath network. There is a path and tunnel under the B98 leading to a private lakeside dock. Accommodation includes a chapel & meeting room seating 100, comfortable lounge with open fire, a 30 seat classroom, and a coffee-shop on site. Public access telephones, basic internet and PA equipment are also available.


Currently, the Schloss is a private house owned by Calvary Chapel and staffed by volunteers. By invitation we can accommodate approximately 100 people for a retreat or conference. The facility comprises Schloss Heroldeck (“the Castle”), and second property, "The Villa", located 50m up the driveway from the main building.

In the Main Building there are 3 dorm style rooms with common bathrooms accomodating upto 30 people. There are 4 family or multiple occupancy rooms with private bathrooms, and there is also a guest room with private bathroom that is a comfortable size for a couple.

The Villa has 12 rooms that have private bath or shower rooms, and a further 5 sharing 2 common bathrooms. All rooms in the Villa are fitted with washstands. The rooms vary in size from double to family size and most are flexible to accommodate couples, families, or a "dorm style" setup. In total the facility may accommodate up to 100 adults depending on room use.

Even during summer season, some rooms may not be available due to other commitments. For groups in excess of 40 adults, we ensure the main facilities will be at the disposal of the group and not shared with other groups.
