Bridge of Earn (Scottish Gaelic: Drochaid Èireann) is a small town in Perthshire, Scotland. Often referred to simply as 'The Brig' (Scots for 'bridge') by its inhabitants. The village grew up on the south bank of an important crossing of the River Earn, whose sandstone bridge existed from at least the early 14th century, when it is known to have been repaired by order of King Robert I of Scotland (1306–1329) (site: NO 133 185). Substantial remains of the medieval bridge (rendered redundant by a replacement, still in use, slightly upstream in 1821-22) survived into the 1970s, when almost all the stonework was demolished, for (allegedly) being in a dangerously ruinous condition. This ancient bridge was a major landmark on the road between Edinburgh (39 miles south) and Perth (4 miles north) for several centuries. The village's oldest houses are to be found lining the road (Back Street/Old Edinburgh Road) leading south from the site of the demolished bridge. Among them are some with 18th-century datestones.
