The Rånäs manor (or Rånäs castle) was built in the 1850s by the Reuterskiöld family at the site of a 17th century manor, torn down after the completion of the present manor. Rånäs manor was designed by the leading architect of the time, professor Per Axel Nyström. Rånäs manor had a charter from 1774 for the yearly production of 1500 ship pounds (260,000 kg) of bar iron. In the fields surrounding the manor grain was cultivated and in its wide-stretched forests coal was bunkered. The manor also included a long low row of houses for the families of the workers employed at the manor, a position which was considered lifelong.
Following the 1932 Krueger Crash the manor was sold to the Municipality of Stockholm and used as a mental hospital until 1985. In 1996 the manor was bought by two private individuals and extensively restored. Since 1998 Rånäs Manor has been a hotel and conference center.
