Devorgilla Bridge

The first bridge was built around 1270 by the Lady Devorgilla of Galloway, a deeply religious and very influential noblewoman who was the great niece of William the Lion and of Malcolm IV. Her son, John Balliol, became King of Scotland in 1292. She is best known for the foundation of Balliol College, Oxford, but in addition she built the Cistercian Sweetheart Abbey, near Dumfries, where in due course she was buried. She also built the convent of Greyfriars in Dumfries, the site of the confrontation between the Red Comyn and Robert the Bruce. Quoted from the Scotland's Oldest Bridges website
