Buechberg, Mountain summit in Schwyz, Switzerland

Buechberg is a mountain that rises between Uznach and Nuolen, reaching 631 meters above sea level. Its steep slopes provide views down to Lake Zurich and the Linth River below.

Around two thousand years ago Buechberg stood as an island in the flat Tuggenersee lake area, and a Roman watchtower was probably built on the hill. In the early 13th century the House of Rapperswil erected Grynau Castle at the nearby Linth crossing. The Linth correction of 1807–1823 reshaped the surrounding landscape.

Local residents maintain a network of walking paths across Buechberg, connecting different communities while preserving traditional routes through the landscape.

Several walking trails cross through the area, with the main route starting near Tuggen and connecting to different viewpoints. The paths are well-maintained and link the surrounding communities together.

The Bollingen Sandstone quarried here has been used since the Middle Ages in Einsiedeln Abbey, St. Gallen Abbey, and Zurich's Fraumünster and Grossmünster; the quarries remain in use. The 380-kilovolt Sils–Fällanden line crosses the hill's northeastern section.
