Alt-Landenberg ruin

Alt-Landenberg ruin stands on a wooded hilltop northwest of Bauma in the canton of Zurich, above the Töss valley. Free to visit and open to everyone, it is a quiet half-day outing in the Zürcher Oberland for anyone who enjoys medieval walls without the crowds.

What is Alt-Landenberg?

The castle is regarded as the home of one branch of the Landenberg family, a noble house of north-eastern Switzerland. The first buildings are thought to predate 1200, and the name Alt-Landenberg appears in records from 1298. Don't confuse it with the family's other strongholds, such as Hohenlandenberg near Wila or Breitenlandenberg, which are separate sites.

A sale document from 1364 shows the castle as a fief of the Abbey of St. Gallen, and it served as the centre of a small judicial lordship. The Alt-Landenberg line died out in 1315, and the estate then passed through other Landenberg branches before Zurich acquired it in 1549. By that point the castle was already falling into decay, and it was never rebuilt.

What can you see on site?

The hilltop is partly shaped by human hands. In the 13th century a large palas, the main residential hall, was raised over older walls, with a courtyard and a well on its western side. Walls reached up to three metres in thickness. Curiously, no trace of a keep has ever turned up. Visitors today can make out the ring wall, the remains of the palas with its shield wall, the well and three gateways. The entrance was relocated several times during the castle's life, and a narrow stairwell was added later.

Archaeologists excavated the site between 1958 and 1963 and the exposed masonry was consolidated, so the layout is easy to read.

How do you get there?

From Bauma railway station it is roughly a 15-minute walk. Bauma lies on the rail line through the Töss valley, so reaching it by train from Zurich is straightforward. The route follows forest paths, so wear sturdy shoes, especially after rain.

When should you visit?

The ruin is open year-round. Spring to autumn is the most comfortable time, with dry trails. In winter the ground can be slippery. There is no café on site, so bring water and a snack. You can easily extend the trip into a longer walk through the surrounding Zürcher Oberland woods and hills.

Frequently asked questions

Is there an entrance fee? No. The ruin is freely accessible.

How long does a visit take? About 15 minutes each way from the station, plus around half an hour among the walls. Plan one to two hours in total.

Is it connected to Hohenlandenberg in Wila? Both belonged to the Landenberg family, but they are different castles in different places. Alt-Landenberg lies in the municipality of Bauma.

What is the highlight? The remains of the large palas, the well, the three gateways, and the oddity that despite its thick walls no keep was ever found.
