Sørup is a manor house and estate located 6 kilometres south of Ringsted, Denmark.

Sørup was probably founded as a manor in the 13th century from land that had previously belonged to the small village of Siøthorp.

The owner was in 1419 Karl Nielsen Sørup and in 1425 it was owned by Jacob Jep Jensen.

His two sons, Jens and Per Ibsen Jepsen, inherited the estate after their father's death.

He obtained the Christian IV's permission to close down the rest of the village of Sørup and place the land directly under the manor.

[1] Luxdorph left Sørup and several other of his estates to his son-in-law, Adam Christopher Knuth.

established the Barony of Conradsborg for their youngest son, Conrad Ditlev Knuth.

[2] In 1797, Conrad Ditlev Knuth was granted royal permission to dissolve the barony and replace it by a family trust (Fideicommissum).

He managed to keep the estate in spite of the agricultural crisis that made many other landowners go bankrupt.
