The old church for Paltamo congregation, the Paltaniemi Church of Paintings, was built in 1726. Another church in Paltamo was damaged in an earthquake in 1626 and a third one destroyed in the Great Northern War as the Russians robbed and burned it in 1716. A Kalevala memorial stone lies on the steps of the Paltaniemi Church of Paintings, symbolising the connection between Kainuu and Karelia. The wooden Paltaniemi Church of Paintings is decorated by paintings in the ceiling and the walls. The bell tower by the church dates back to 1769. https://www.visitkajaani.fi/en/products/paltaniemi-church-paintings/

Kajaani Art Museum was opened to the public in April 1993. The museum's exhibition rooms are located in the former police house designed by architect Eino Pitkänen. Completed in 1936, the building is an example of pure functionalist style. http://www.kajaani.fi/taxonomy/term/4800

The Kajaani castle was built on the Ämmäkoski island of the Kajaani river in the centre of Kajaani, Finland, in the 17th century. It functioned as a governing centre, a prison, and a refuge for residents during times of persecution. The most famous prisoner in the castle was the historian Johannes Messenius, who was forced to live in the poor conditions of the castle from 1616 to 1635. Construction of the Kajaani castle began in 1604 and was completed in 1619. At first the castle only consisted of a stone wall, two round towers, and wooden buildings in the yard inside the castle. The second phase of construction was ordered by Count Peter Brahe which began in the 1650s and was completed in 1666. Upon completion many of the original wooden structures had been replaced with stone and the castle had become a fortress. During the “Greater Wrath”, Russian forces kept the castle under siege for months, and upon its surrender they blew up much of the fortress, transporting the inhabitants to Russia to be imprisoned. Kajaani Castle is thought to be the smallest stone castle, and the most northernmost, in the world. https://www.discoveringfinland.com/destination/kajaani-castle/
