Koiviston kartano

Koiviston kartano is a manor house on the Kokemäenjoki River in Pori, featuring grey granite stone structures for agriculture and historic stables. The buildings form a complex that demonstrates the layout of an earlier working farm.

King Gustav Vasa established this estate as a royal manor in 1557 at the river mouth near the medieval town of Ulvila. In the 18th century, Professor Johan Kraftman acquired the property and introduced agricultural innovations there.

The name comes from the birch trees that once covered the land around the estate. Visitors can still sense how the riverside location shaped daily life and farming practices in earlier times.

The estate now belongs to the City of Pori and can be viewed from the outside, with reconstructed stables from 2000. Visitors should note that the riverside location means the grounds can be wetter during certain seasons.

The shoreline has retreated about 15 kilometers due to land elevation and river sediment buildup over centuries. What was once a waterfront location is now far inland from the coast.
