Leutra (Jena)
Leutra is the name of a small river or stream that flows through Jena, Germany. It is a tributary of the Saale river, into which it empties within the city limits. The Leutra is characterized by its relatively short length and its course through both urban and more natural landscapes near Jena. Its name is derived from the Old Slavic word lutra, meaning "clear" or "bright stream". The valley carved by the Leutra has historically influenced the development and geography of the region, contributing to the landscape and providing a source of water. While not a major river, the Leutra contributes to the local ecosystem and is a feature of the Jena environment. Its course has been modified in parts by human development and infrastructure.
