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.
