The exquisite Rosslyn Chapel is a masterpiece in stone. It used to be one of Scotland's best kept secrets, but it became world-famous when it was featured in Dan Brown's the Da Vinci Code.
Art historian Helen Rosslyn, whose husband's ancestor built the chapel over 500 years ago, is the guide on a journey of discovery around this perfect gem of a building. Extraordinary carvings of green men, inverted angels and mysterious masonic marks beg the questions of where these images come from and who were the stonemasons that created them? Helen's search leads her across Scotland and to Normandy in search of the creators of this medieval masterpiece.
