Martenastate in Cornjum, Netherlands, is an ancestral estate first owned by the noble family Martena, also written as van Martena, or even Martna. This family belonged to the Dutch nobility. The building is now a museum.
The first mention of a stins at the Martenastate in Cornjum dates back to 1468, when the family Martena lived there. The last male ancestor of the Martena line was Doecke van Martena, who died in 1605.
After 1605, the Martenastate in Cornjum was owned and occupied by a succession of other noble families: the Aylva family, the Burmania family, and the Vegelin van Claerbergen family.
