Gretna Green is a village in the south of Scotland famous for runaway weddings. It is in Dumfriesshire, near the mouth of the River Esk and was historically the first village in Scotland, following the old coaching route from London to Edinburgh. Gretna Green railway station serves both Gretna Green and Gretna. The Quintinshill rail crash, the worst rail crash in British history (226 recorded deaths), occurred near Gretna Green in 1915.
Gretna Green sits alongside the main town of Gretna. Both are accessed from the A74(M) motorway and are near the border of Scotland with England.
