Burg Strahlegg, Medieval castle ruins at Lake Walensee, Switzerland.
Burg Strahlegg is a castle ruin on the shore of Lake Walensee featuring a remaining stone tower. The structure displays a square foundation and uses roughly cut limestone blocks typical of its medieval construction period.
The fortification was built on the remains of a Roman watchtower from the 1st century and later served as a strategic outpost in the region. Its active use ended in the late 14th century when it was destroyed during a regional conflict.
The fortress served as a watchtower to monitor the lakeshore and control trade routes passing through the valley. Visitors standing here today can still sense the strategic purpose that once made this location valuable for regional powers.
The site is directly accessible from the lakeshore at ground level with clear views of the surrounding water and valley. Sturdy footwear is advisable since the terrain can be uneven and conditions may vary with the weather.
Excavations revealed that visible stepped stone foundations from a Roman-era installation remain beneath the medieval masonry. These rare layers show how different periods of occupation literally built upon one another at this location.
