The present Torshälla Church building was originally erected in Romanesque style during the 12th century at the old heathen sacrificial place of Torsharg. Torshälla was granted city rights in 1317, making the old church insufficient for the growing population of the town. A newnave was added to the west, transforming the old nave into a choir.
During the 15th century, the church tower, church porch and vaulted ceiling were added. The tower spire was rebuilt in 1614 to reach a height of 92 meters, making Torshälla Church a landmark used for navigation on nearby Lake Mälaren and one of Sweden's tallest buildings at the time. After the tower spire and the roof were destroyed in 1873, in a fire caused by a lightning strike, they were replaced with the present, lower brick gabled roof.
Wooden sculptures depicting St. Bridget of Sweden, St. Catherine of Vadstena, Saint Gertrude and Saint George are displayed in the church. The preserved 15th century ceiling paintings are attributed to the master painter Albertus Pictor and include the oldest known depiction of eyeglasses in Sweden, showing Abraham as a reading man wearing glasses.
Along the south wall a burial vault was built during the 17th century for the family of the early industrialist and founder of Eskilstuna's iron-working industry Reinhold Rademacher (1609-1668).References:
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.
