The original small church was built from 1341 to 1346 to replace the old fort on the site. From 1480 to 1483 the city added a tower and from 1493 to 1504, a new nave was added.
After the Protestant Reformation in 1529, the Nydeggkirche was transformed into a warehouse for barrels, timber and grain, but in 1566 again served as worship space. Beginning in 1566 it was cleaned out and minor renovations made to the windows and walls. However, in 1568 the bell tower roof caught fire and was destroyed. The new roof was finished and the damaged clock work repaired by the end of May 1571. The large wrought iron cross which tops the main spire was built by Caspar Brükessel during the same time. The current tower's appearance mostly dates back to the 1571 reconstruction.
The later changes to the tower were fairly minor. For example, in 1625 four small embrasures or firing slits were broken out of the tower to help defend the city gate and in 1631 eight copper waterspouts were added to the roof.
Until 1721 it was a branch church of the Münster of Bern. Today's congregation forms part of the Reformed Churches of the Canton Bern-Jura-Solothurn.
In 1863, the church was extended to the west and an entrance from the Nydeggbrücke (Nydegg Bridge) was added. Then, from 1951 to 1953 a total renovation happened.
In 1956, bronze reliefs by Perincioli were inspired by medieval role models in front of San Zeno in Verona and the Cathedral of Hildesheim.References:
Dating from the 15th century, Kisimul is the only significant surviving medieval castle in the Outer Hebrides. It was the residence of the chief of the Macneils of Barra, who claimed descent from the legendary Niall of the Nine Hostages. Tradition tells of the Macneils settling in Barra in the 11th century, but it was only in 1427 that Gilleonan Macneil comes on record as the first lord. He probably built the castle that dominates the rocky islet, and in its shadow a crew house for his personal galley and crew. The sea coursed through Macneil veins, and a descendant, Ruari ‘the Turbulent’, was arrested for piracy of an English ship during King James VI’s reign in the later 16th century.
Heavy debts eventually forced the Macneil chiefs to sell Barra in 1838. However, a descendant, Robert Lister Macneil, the 45th Chief, repurchased the estate in 1937, and set about restoring his ancestral seat. It passed into Historic Scotland’s care in 2000.
The castle dates essentially from the 15th century. It takes the form of a three-storey tower house. This formed the residence of the clan chief. An associated curtain wall fringed the small rock on which the castle stood, and enclosed a small courtyard in which there are ancillary buildings. These comprised a feasting hall, a chapel, a tanist’s house and a watchman’s house. Most were restored in the 20th century, the tanist’s house serving as the family home of the Macneils. A well near the postern gate is fed with fresh water from an underground seam. Outside the curtain wall, beside the original landing-place, are the foundations of the crew house, where the sailors manning their chief’s galley had their quarters.
