Very beautiful farm.
The main building is a red-painted wooden building with two floors under a hipped roof. The house was probably built in 1606, perhaps even earlier, and has, among other things, a well-preserved Renaissance stove bearing the year 1606. It then formed the southern wing of a main building that disappeared at the end of the 17th century. At the exit from the estate, which is bordered by an avenue, there are two red wings with gable roofs. They are of a later date and were used as workers' housing. To the east and west of these there are further older residential buildings and outbuildings added during different periods. Behind the main building are two loft sheds that were moved here from Järshammar and Västra Fyrby in Öja parish. The smithy and the carpenter's cottage were built in 1858 and bricked in slag.
Wikipedia tells us: Biby was previously a manor and a manor in Gillberga parish, Västerrekarne district and Eskilstuna municipality. The farm is located twelve kilometers southwest of Eskilstuna. The main building in Biby dates from the 17th century and is one of the oldest preserved wooden residential buildings in Södermanland.
Biby has been known since the 15th century, and belonged from the end of the 16th century until 1676 to the Stiernsköld family, and then to the Sparre family. In 1782, Biby was purchased by Baron Gustaf Celsing, and in 1788 became fideicommiss within his family. Since the last fideicommissary, equestrian master Fredrik von Celsing, died in 2008, the liquidation began. His heirs wanted to finance the inheritance by selling parts of the property. In 2013, Johan Klingspor at Stora Sundby bought the farm with associated land of around 1,200 hectares. In 2018, the Fideicommissnämden gave permission for probate. The fideikommisset is thus discontinued.
There is a unique collection of Turkish paintings and documents from the time of the Celsing family that Turkish diplomats, the so-called Turkish collection, would sell on the international market after the fideicommission was dissolved. The government has, following referrals from, among others, the National Museum, the National Antiquities Office and the National Archives, decided partly that the state would not redeem the Turkish collection, and partly that the state would redeem the mission archive that was included in the fideicommissis. The Turkish collection is now in Qatar.
