The house is already known from 1682, when it was owned by
Byfoged Mads Christensen. It is probably only slightly older. From 1829 to 31 it was owned by titular Privy councilor Jacob Mandix, and after his death in 1831 by his daughter,
Lucie Mandix, the wife of
Bernhard Severin Ingemann and one of Denmark's first female painters. Hector Frederik Janson Estrup, who had been appointed to director of
Sorø Academy in 1831, acquired the building in 1833. He converted it into two residences available on grant for widows after teachers at the school. Estrup was married to a member of the Scavenius family and after her death to her sister. Estrup lived at Urnes gård, at 9 Søgade, another listed property in Sorø. He was the father of
Jacob Brønnum Scavenius Estrup, Danish
Council President from 1875 until 1894. ==Architecture==
