Kienbaum

Kienbaum is a district of the Brandenburg municipality of Grünheide, southeast of Berlin in the Oder-Spree district. In July 2011, the village had 294 inhabitants. The rural and secluded village is today primarily known for the Federal Performance Center Kienbaum of the German Olympic Sports Confederation located by Lake Liebenberger See.
The village is located upstream of the Löcknitz, which separates Barnim from Lebuser Land as part of the Buckower Rinne, and had some strategic significance in the Middle Ages as a border village. In particular, the present part of Liebenberg, which was already mentioned as deserted in 1247, likely played an important role in securing the so-called Liebenberger Löcknitz Pass during the period of German eastward settlement when the Diocese of Lebus was still under Polish influence. Kienbaum itself, located east of the Löcknitz in contrast to Liebenberg, is first mentioned in 1405 in the Stiftsregister Lebus, but by at least 1452 belonged to the Monastery of Zinna located near Jüterbog. With a customs station on the trade route between Berlin and Frankfurt/Oder and with a post station on a postal road, Kienbaum's significance was maintained in the following centuries. In the late Middle Ages and early modern period, Kienbaum gained a reputation as a site for forest bee farming; every year, a "bee convention" was held in the village. Mysterious fires in the 1890s inspired the writer Gerhart Hauptmann to his tragicomedy The Red Rooster, which is commemorated by a Hauptmann monument featuring a rooster next to the village church, which was newly built in 1908/1909 and is now a listed building.
