Spiez Castle sits on a peninsula on Lake Thun and is considered a symbol of the municipality of Spiez. In its historic rooms, you can experience the transformation from a medieval fortress to the patrician residence of notable Bernese noble families. The castle museum features interactive exhibits, staged rooms, and original furnishings spanning several centuries. From the castle tower, you get a 360-degree panoramic view over Lake Thun, vineyards, and the surrounding mountains. The adjacent Romanesque castle church and well-maintained park with garden areas complete the lakeside ensemble.
