About two thousand years ago, Buechberg formed an island in the former flat Tuggenersee lake area, and there was probably at least one Roman watching tower on the hill established.
In the early 13th century AD the House of Rapperswil built the Grynau Castle at the most important and strategically river crossing over the Linth river nearby the then nearly landed lake.

From Tuggen there's also a historical road heading from the former granary at the Grynau Castle over the Buechberg hill towards Siebnen.

The taming of the Linth river (Linthkorrektur) from 1807 to 1823 once more changed the landscape, which is also very popular for hiking.
