Tersløsegaard is a manor house located close to Dianalund, Sorø Municipality some 60 kilometres southwest of Copenhagen, Denmark.

He left it to Sorø Academy and it has now been converted into a self-owning foundation and contains a Holberg exhibition.

Members of the Passow family owned Tersløsegaard with few interruptions until the beginning of the 16th century when it came into the possession of the Bishopric of Roskilde.

It was after the Reformation confiscated by the Crown and then granted to Mads Eriksen Bølle who had assisted Christian II in the defence of Copenhagen.

Many landowners immediately purchased new cattle and lost then again in the next outbreak but Holberg replaced them with sheep and horses.

They was granted royal approval of "Four former Soranian Alumni's Preservation of Holberg's Widow Seat at Terskøsegaard" in 1862.

The estate was managed by a board consisting of the count of Frijsenborg, the barons of Lehn and Juellinge and the owner of Tersløse.

After G. F. R. Grüner's death in 1890 Tersløsegaard once again fell into neglect and the remaining land was sold off.

The Soranian Society of former students at Sorø Academy established a fubnd-raising committee.
