The Chapel of St. Mary and St. Nathalan is a ruined chapel overlooking the North Sea immediately north of Stonehaven. The founding of this Christian place of worship is associated with St. Nathalan, who lived circa 650 AD. It was dedicated in 1276 by William Wishart, Bishop of St Andrews, and probably stands on the same site as St Nathalan’s early church. The chapel was never a parish church but was included within the parish of Fetteresso. Several Scottish monarchs, in particular James IV, frequently worshipped here and gave generous donations to the chapel.
The chapel is at the point where the Highland Boundary Fault meets the sea and so is on the dividing line between the highlands and lowlands of Scotland. The Chapel of St. Mary and St. Nathalan is one of the oldest surviving structures in Kincardineshire.
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.
