Bavariabuche, Historic beech tree in Altmannstein, Germany

The Bavariabuche was a European beech (Fagus sylvatica) at Stenzenhofer Straße, 350 metres northwest of Pondorf in the municipality of Altmannstein, Upper Bavaria. Its trunk had a circumference of nine metres and the tree stood 22 metres tall. The crown measured over 30 metres across and covered about 750 square metres. It is thought to have grown from two or three beeches that stood about one metre apart.

The tree developed over centuries at its location and became a recognized landmark for the region. In 2013, a severe summer storm destroyed it completely.

The tree's fame grew through a Bavarian television feature in the early 1980s made with local chronicler Franz Fersch. In 1987 it appeared on a collector's plate by Ernst Wetteroth, and photographer Willy Matheisl made a twelve-month series in 1992. Since 2022 the "Garten der Bavariabuche" has marked the site with information boards.

The site lies on Stenzenhofer Straße, 350 metres northwest of Pondorf in the municipality of Altmannstein, in the Altmühltal Nature Park. Since 2022 the "Garten der Bavariabuche" has stood there, with information boards on the tree, its surroundings and its history. The area around the trunk was fenced in 1997 to protect the soil and roots; the wood is not to be cleared, and the spot is meant to become a deadwood biotope.

Before its destruction, this tree was one of Germany's most photographed trees and appeared in many regional publications. Its distinctive shape made it a recognizable symbol of the area.
