The Eyneburg was built on a hill high up above the Göhl. It is one of the few hilltop castles in the former Duchy of Limburg. The name Eyneburg or Eyneberghe comes from a family to whom this manor house belonged in the 13th century. The name 'Emmaburg', used for the complex in the vernacular, goes back to a legend according to which a daughter of Charlemagne, Emma, lived there for a time. However, this association, not tenable in historical terms, was not made until the 19th century. Today the Eyneburg is privately owned. Its valuable interior was auctioned off in 1958.
