Auld Brig, Keith
Built in 1609 over the River Isla to carry the main road north, it is just wide enough for horses and pedestrians to use. Imagine the scenes it has witnessed during hundreds of years, including Daniel Defoe on his wanderings and Jacobite troops .
This is the oldest surviving iron bridge in Scotland. Thomas Telford listened to the locals when designing the bridge and built it higher than planned. It withstood the floods of 1829, when the River Spey rose by nearly 5 m.
