Keith Old Bridge, also known as Keith Auld Brig was built in 1609. It is the oldest surviving dated bridge in Moray and is a Category A listed building.
Keith Old Bridge is built of granite rubble, and spans the River Isla in a single segmental arch, linking the higher northern bank to the lower southern one, where it is widely splayed. On its eastern flank it bears a worn carving of the coats of arms of Thomas Moray and Janet Lindsay, and on the west there are date stones showing 1609, the year the bridge was built, and 1822, when repair work was carried out on it. Currently used only by pedestrian traffic, it is approximately 2.8 metres wide, with a span of 8.2 metres.
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.
