The wooden church of Pihjalavesi was built between 1780-1782. In 1778 small village of Pihjalavesi requested to build their own church, because it was long distance to nearest church. The parish of Keuruu denied the request, but the building of smaller chapel was allowed without any public funding. Local inhabitant built anyway a church and sold grain and tar to fund it. When the church was completed, local vicar got admonition from the chapter.
Pihlajavesi Wilderness Church was designed by famous church builder Matti Pärnä-Åkerblom. There are many legends of church, you can for example find figures of people in the inside wall of the church. Remarks are probably originated from the people reclining to the wall during worships.
The cemetery surrounding church was established in 1785 and used until the beginning of the 20th century. Some parts of the church were renovated in 1870s and again in 1930s. It’s open in summertime and popular venue for worships, concerts and weddings.
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
