Jacob Huitfeldt and his wife Lisebeth Friis built the present manor house that was constructed by Hans van Steenwinckel the Elder.

In 1654, Joachim Gersdorff, the widower after Huitfeldt, sold the Berritzgaard estate to Hans Wilhelm von Harstall, who was the "Chosen Prince Christian's" stable master.

Now in possession of the Guldborgland Barony, Colonel Henrik Christian Rosenoern was given the title "baron" with the name Rosenoern-Lehn for him and his descendants to bear.

Christiane Henriette had previously decided to move the headquarters of the Barony of Guldborgland to the more beautifully situated Oreby Estate and to restore the rather rundown castle there.

To carry this out, Poul Lehn's will, in which he had set aside a considerable sum of money to restore Berritzgaard's big detached wing, had to be changed.

The run down wing that was supposed to be restored was instead demolished, and Hans van Steenwinckel's fine house was allowed to stand untouched by changing architectural fashions.

One of the larger known renovations of Berritzgaard was in the 1890s where the existing leaded lights were added to mimic the Rosenborg Castle in Copenhagen and the windows on the first floor were shortened so they would "stand" on the decorative limestone border, which is set into the redbrick wall all around the house.

This avenue frames the garden room beautifully and by making a "false" perspective gives an impression of a far view in an otherwise completely flat landscape.
