Rikstens gård, Manor house in Botkyrka Municipality, Sweden

Rikstens gård is a plastered two-storey manor house built in 1913 to designs by architect Knut Nordenskjöld, standing on the foundations of a 17th-century predecessor near the northern shore of Bysjön in Tullinge. Its west facade has two symmetrical tower-like projections and is flanked by two small pavilions that were once wings of the older house. Two detached wings by Nordenskjöld stand to the west, and a large yellow-plastered stone barn lies east by Pålamalmsvägen.

Riksten is first mentioned in a letter from 1356. In 1615 the estate received säteri rights while owned by Peder Nilsson Gyllenax, who had been granted the property for his service as treasurer to Karl IX and Gustav II Adolf. The main building was rebuilt in 1662 by Erik Fleming, burned down in 1809, and replaced by a wooden house with two wings. The present brick main building was erected in 1913 to designs by Knut Nordenskjöld, on the foundations of the 17th-century building.

The manor reflects National Romantic architectural ideals that shaped early 20th-century Swedish building design. Its distinctive towers and symmetrical layout show how architectural tastes of that era were expressed in the countryside.

The manor stands on the northern shore of Bysjön in Tullinge, with the main building set back from the water behind a low stone wall and steps. The grounds are private; the buildings and the surviving east–west axis with its flanking wings are best seen from the public road and the lakeside path.

Archaeological excavations on the grounds have revealed Stone Age artifacts and two burial fields from the Late Iron Age. These discoveries indicate continuous human settlement spanning thousands of years.
