The headwaters of the Dullan Water, the Burn of Favat and the Corryhabbie Burn, meet at Milltown of Laggan before flowing as the Dullan, northeastwards to Dufftown. There are distilleries adjacent to both rivers, notably that producing Glenfiddich whisky. The town was originally named Mortlach in the Middle Ages, until the 19th century when the Earl of Fife built the town as a housing for soldiers returning home from war. He named the town Dufftown. Dufftown also hosts a highland games event every July which attracts many tourists. Dufftown's notable buildings include Balvenie Castle, which was partly built with stones from the ruins of nearby Auchindoun Castle. The street plan of Dufftown is mainly four main roads meeting at the clock tower; previously a prison but now a tourist information centre. The Glenfiddich Distillery is a Speyside single malt Scotch whisky distillery owned by William Grant & Sons in Dufftown, Scotland. Glenfiddich means ‘Valley of the Deer' in Gaelic, hence the presence of a stag symbol on Glenfiddich bottles.
