Skanelaholm Castle 

Skanelaholm Castle is a castle in Sigtuna Municipality , Stockholm County , Sweden. Skånelaholm lies in a very old cultural landscape and may have been a crown estate manor during the early Middle Ages. The estate is mentioned for the first time in written sources in 1276, when it was sold by King Magnus III to Sko Abbey, a monastery at the site of present-day Skokloster Castle. It remained in the possession of the abbey until the Reformation, when it was confiscated by King Gustav Vasa.

It thereafter was a crown estate manor for a long time. In 1618 it was let to Johan Patkull, a nobleman of Livonian extraction in service of the Swedish king. The estate however remained the property of the crown until 1641 when it was bought by Andreas Gyldenklou, who built the presently visible main building. It stayed in the Gyldenklou family until the 1690s, after which the estate changed ownership several times until 1742, when it was acquired by Frans Jennings.
