The Church of St Hywyn, Aberdaron, Gwynedd, Wales, is a parish church dating from the 12th century. Its origins are earlier, as a clas church from the 5th to the 7th centuries. Further building, including the construction of the second nave, took place in the late 15th or early 16th centuries. Its importance was as an embarkation point for the abbey on Bardsey Island which became a significant site of pilgrimage in the Middle Ages. The Reformation saw the church's decline, and by the 19th century it was a ruin. In the 1850s a new church, Eglwys Newydd, was constructed inland, but proved so unpopular that St Hywyn's was restored.
The church comprises two naves, of equal length but of differing dates; the Northern is largely 12th century while the Southern dates from the 14th century. The building is constructed of rubble with slate roofs and a bellcote. The interior, which was refurbished in 2006 has a hammerbeam roof. The internal arcade is from the 15th century. Two carved boulders within the church commemorate a pair of 5th or 6th century priests, Veracius and Senacus.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
