Roslin (formerly spelt Rosslyn or Roslyn)[2] is a village in Midlothian, Scotland, 11 kilometres (7 mi) to the south of the capital city Edinburgh.

The theory that it is a corruption of Rose line, a supposed medieval meridian passing through Paris and Rosslyn Chapel, is fanciful.

[7] William Morris visited in March 1887, noting in his Socialist Diary that Roslin was "a beautiful glen-ny landscape much spoiled ... by the misery of Scotch building and a manufactory or two".

On the north-western side of the village used to be Roslin Institute, a biological research establishment, where in 1996 Dolly the sheep became the first animal to be cloned from an adult somatic cell.

The elaborately carved chapel has long been associated with the Knights Templar and the Grail legend,[9] and featured in the best-selling book The Da Vinci Code.
