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.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
