The Itä-Häme Museum in Hartola

The Itä-Häme Museum covers 7 parishes. It was founded on the initiative of Maila Talvio, a Finnish authoress born in Hartola. The museum is housed in the former Koskipää mansion. The Koskipää family settled in Hartola during the fourteenth century and in 1580, after Sipi Henrikson had gained possession of the neighbouring farms, the mansion was built. In 1639 his son Klaus was granted a title and took the name of Silferbögel.

In 1677 the house was transferred to the Tandefelt family of Sysmä and they remained the owners until the beginning of the 19th century. From the Tandefelts the house passed into the hands of the von Gerdten family.

At its largest the Koskipää estate measured 25000 hectares (about 75000 acres), and there were over a hundred tenants (crofters).
