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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
