Charlottenborg slott, is a country house or manor house rather than a castle, on the shores of Motala ström, Östergötland, Sweden. The house was built in the mid 17th century by Ludvig Wierich Lewenhaupt and named in honour of his wife, Charlotte von Hohenlohe-Neuenstein. Charlottenborg has been home to both Adam Ludwig Lewenhaupt and Daniel Fraser.
The mid-seventeenth century house that is shown in an engraving in Erik Dahlberg's monumental topography, Suecia antiqua et hodierna, was rebuilt in more modern fashion in the eighteenth century.
The castle is haunted by the Lady in White and the Lady in Black. The Lady in White is said to be the first owner Charlotte Lewenhaupt and she is often seen by the staff and visitors. Today the castle houses Motala Museum with historical exhibitions.
