Hartenfels

Hartenfels is an Ortsgemeinde – a community belonging to a Verbandsgemeinde – in the Westerwaldkreis in Rhineland-Palatinate, Germany. The community belongs to the Verbandsgemeinde of Selters, a kind of collective municipality.
Hartenfels Castle was first mentioned in old writings in 1249. The community is known for its castle ruins, of whose former shape only a few walls and one tower now remain. It was built in the 13th century to keep watch over the nearby trade road leading from Frankfurt to Cologne. In dialectal speech, the ruins bear the name Schmanddippe. In 1999, the community celebrated 750 years of existence. Seven years later came a chronicle.
