Tranekær Castle is lived in by the Ahlefeldt-Laurvig family and is the oldest lived-in building in Denmark. The Castle first came into the hands of the Ahlefeldt-Laurvig family in 1659 as part of the dowry when Margrethe Dorothea Rantzau, daughter of Christian Rantzau, married Frederik Ahlefeldt. In 1672 Frederik Ahlefeldt was elevated to Count. He united Tranekær and his other holdings into the County of Langeland.
Today Tranekær Estate is a modern agricultural and forestry enterprise farming an area of 4.436 Acres. The farming is traditional with production of grain and seed crops. Including leasing and care agreements, crops are grown on 2.752 Acres, and it has various AE grass agreements and biotope plans for wild life covering another 740 Acres. The forestry is driven in a traditional manner. It is possible to lease the castle in connection with meetings, conferences and company dinners, at which accommodation is also an option. www.tranekaergods.dk
