Næsbyholm is a manor house and estate located east of Tybjerg Lake, between Sorø and Glumsø, in Næstved Municipality, some 70 km (43 mi) southwest of Copenhagen, Denmark.

[1] Næsbygaard was granted status of a manor at some point during the reign of Margrethe I (1353–1412), after Olufsen had acquired more land in the area from the Diocese of Roskilde in exchange of property elsewhere.

The two shares that belonged to her sisters, Ingebrog and Margrethe, were confiscated by Christian II because their spouses had supported the Scanian uprising.

In 1575, she married Steen Ottesen Brahe, a diplomat and advisor both to Frederik II and Christian IV.

Steen Brahe constructed a new main building in 1585 and also increased the size of the estate through the acquisition of more land.

However, Birgitte Rosenkrantz Brahe died in labour shortly after the new main building had been completed and her husband then moved away from the estate but nonetheless kept it until his death.

Also in 1663, Frederick III granted a property north of Copenhagen to Bjelke and it was later named Edelgave after his wife Edel Ulfeldt.

He joined the army a few years later, was promoted through the ranks, and ended up spending much of his time in foreign service abroad.

In 1709 and 1710, Næsbyholm and nearby Bavelse were acquired by Frederik IV for his mistress, Charlotte Helene von Schindel, who was given the title Countess of Frederiksholm.

She initially stopped at Fyn and claimed to be pregnant with Frederick's child, but the pregnancy turned out to be false.

Charlotte Helene von Schindel hosted a vivid social life at her estate and entered into a relationship with the noble Ernst G. Bülow, with whom she had a child.

To facilitate transportation of timber from his forest at Næsbyholm, he canalized the Suså River from Bavelse to Næstved.

He was the son of a merchant from Flensburg but had moved to Copenhagen in an early age where he had made a fortune on speculative investments during the war years.

[7] Rønnenkamp had no children and therefore left his estates to his wife's grandson, P. Christian Howden (1854–1930), who assumed the last name Howden-Rønnenkamp.

The manor house is known for the Næsbyholm Ceiling, originally decorated with four allegorical frescos of the four seasons, of which only "Winter" and "Spring" have survived.
