The Lutheran Church of St. Reinold (Reinoldikirche) is dedicated to the patron of the city. The church was built as a palatine church in the Ottonian era. The present building is a late Romanesque church with a late gothic quire. St. Reinold's was built from 1250 to 1270, and is located in the centre of the city, directly at the crossing of the Hellweg (a historic trade route) and the historic road from Cologne to Bremen. St. Reinoldi's congregation is a member of the Evangelical Church of Westphalia, an umbrella comprising Lutheran, Reformed and united Protestant congregations.
Efforts to complete the tower of St. Reinold's were renewed in 1443. After its completion in 1454, it was 112m tall. The polygonal spire was renovated the first time in 1519. The apex of the church was now about seven metres higher. In 1661, the tower collapsed after being damaged during an earthquake. The foundation for the new tower was laid 1662, and the building was completed 1701, with a baroque ornament on the top.
The church was heavily damaged in World War II. Since the reconstruction the tower now bears a hood with baroque features. These features supply a visual and harmonious connection between the original style of the church and its appearance after reconstruction. The tower can be visited, up to the first platform by the bell tower.
On the inside there is a large set of bells. The heaviest bell, weighing 6.500 kg, is the largest cast steel bell in Westphalia.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.
