Rånäs Manor, Manor house in Norrtälje Municipality, Sweden

Rånäs Manor is a manor house on the northern shore of Lake Skedviken in Uppland, about an hour's drive north of Stockholm. The main building, designed by Per Axel Nyström, was built between 1833 and 1844 in late Empire style with Italian influences. Its rectangular plan has a three-storey central section flanked by two narrow four-storey side sections, and two low two-storey wings are attached to the main building. Because the house stands on a slope, the west facade has one storey fewer than the east.

Rånäs was bought in 1674 by court marshal Joakim Wilhelm von Lützow, who made it a säteri; the main building was then a two-storey wooden house with a säteri roof northeast of the present one. In 1772 the estates passed to bergsråd Jean le Febure, owner of Gimo bruk, and Rånäs bruk received its charter in 1774, becoming Uppland's southernmost Walloon ironworks. The current manor was built 1833–1844 to drawings by Per Axel Nyström for Axel Didrik Reuterskiöld; when it was finished in 1844 the old manor was torn down and the founder's 16-year-old grandson Oskar Axel Reuterskiöld became its owner. Ironworking ceased in 1894.

Rånäs bruk received its ironworks charter in 1774, making it the southernmost Walloon forge in Uppland. Iron production continued for just over a hundred years and ended in 1894. The estate's dairy, built around 1895, made butter and full-fat cheese, and Rånäs won a prize for its manor cheese at a Stockholm cheese exhibition in 1904.

The estate today functions as a hotel and conference center, offering guests rooms, dining options, and wellness amenities. Its location near Stockholm makes it easy to reach, and the surrounding area provides walking and outdoor activities around the lake and forests.

The manor's charter of 1774 allowed an annual output of 1,500 ship pounds (260,000 kg) of bar iron. The flat roofs of the two side wings are edged with wrought-iron railings, probably made by the estate's own blacksmiths.
