Mustio manor ("Mustio Castle", "Svartå Slott") was built in 1783-1792 by Magnus Linder, the owner of the local ironworks. There had been an older manor from the 17th century, but it was dismantled when the present one was built. The manor represents the neoclassical ("kustavilainen") architecture.
Today Mustio is a countryside hotel. There are also the old ironworks and one of the biggest private historical parks of Finland.
The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
