Alpengarten Schachen, Alpine garden at Wetterstein massif, Germany

Alpengarten Schachen is a high mountain garden in the Bavarian Alps at approximately 1860 meters elevation. It holds over 1000 plant species collected from mountain ranges around the world, including specimens from the Alps, Himalayas, and other remote peaks.

Karl von Goebel, director of the Munich Botanical Garden from 1891 to 1931, agreed with the Garmisch-Partenkirchen municipality in 1900 to create the garden; it opened on 13–14 July 1901 on a site of initially 7000 square metres. Goebel had a blockhouse gardener's dwelling built in 1900, which still stands, and the garden was reachable via the Königsweg, a gravel road laid out 30 years earlier for the building of Schachenhaus for King Ludwig II.

The garden's name comes from the Schachentorkopf, the saddle-shaped peak to its east. Since 1901 two gardeners have come each year from Munich between mid-June and early September to tend the plants. The blockhouse they built in 1900 still stands, and from 1901 to 2015 seventy gardeners worked here.

The garden is reached on foot via the Königsweg, a gravel track built about 30 years before 1901 for King Ludwig II's Schachenschloss and passable by horse-drawn carts. Two gardeners from the Munich Botanical Garden stay from mid-June to early September; the gardener's house has had electricity and sanitary facilities since 2015.

In 1935 the ecophysiologist Friedrich von Faber set up an altitude laboratory on the ground floor of the blockhouse, equipped with precision balances, microscopes, glassware and chemicals; it was used only until 1939. Today seeds are still harvested every year for the international seed exchange of the Munich Botanical Garden.
