Ruthwell is a village and parish on the Solway Firth between Dumfries and Annan in Dumfries and Galloway, Scotland. Ruthwell's most famous inhabitant was the Rev. Dr. Henry Duncan. He was a minister, author, antiquarian, geologist, publisher, philanthropist, artist and businessman. In 1810, Dr. Duncan opened the world's first commercial savings bank, paying interest on its investors' modest savings. The Savings Bank Museum tells the story of early home savings in Britain. The village was once served by Ruthwell railway station.
