Rönneholm Castle, Renaissance castle in Eslöv Municipality, Sweden.

Rönneholm Castle is a three-story manor house in Eslöv Municipality, Sweden, with a facade featuring French Renaissance details. The building sits within a landscaped park with wooded areas surrounding the main residence.

The estate has roots in the early Middle Ages and took its current form after a major reconstruction in 1811. A third floor was added in 1882, permanently changing the building's silhouette.

The estate's history reaches back to the early Middle Ages, though the original construction period is unknown. The present building was rebuilt in 1811 in the French Renaissance style and remodeled in 1882 with a third floor added. For much of the 20th century the castle served as a sanatorium.

The estate can be reached on foot and has parking available for those arriving by car. Visitors should allow enough time to walk through the full park at a comfortable pace.

The sanatorium use is not visible from outside: the white-plastered facade with its rows of dark-framed windows and the flat-roofed columned portico on the right give no hint of it. The 1941 fire led to a restoration, after which the building continued in that role for much of the century.
