Jäneda hill fort was a hill fort used from the 10th to the 12th century. It consisted by a rampart reaching approximately 3 metres (9.8 ft), surrounding a triangular courtyard. There were two towers at the entrance at the southern end and, possibly, another tower at the northern end. The fort was surrounded by a moat.
Jäneda manor was founded as an estate before 1510. The estate has belonged to several different aristocratic families. The present building was built 1913-1915 in an eclectic Art Nouveau style with strong neo-Gothic influences. In 1922, the interiors were rebuilt after designs by architect Anton Lembit Soans. Estonian composer Urmas Sisask has furnished a planetarium at the top of the tower.
The manor is now converted to a museum and conference center. Ugri.info seminar on Finno-Ugric languages and infosystems was held at the manor on either 3 December 2004 or March 12, 2004.
