Edinburgh Castle's walls, buildings and ramparts will be transformed by projected light and sound in this 90-minute historical walking tour, running over six weeks during the Christmas season.
A team of local designers with longtime experience working with light and the moving image have created a show that draws on "the history, geology, mythology and the sheer drama" of the castle to "excite, entertain and enlighten".
Edinburgh Castle has been used before for projected light shows - the Edinburgh Military Tattoo uses light projection as part of its show and the opening event of Edinburgh International Festival 2016 was a mesmerising light show Deep Time, projected on the outer castle and castle rock.
But this is the first "immersive" walking tour that uses light projection to delve into Edinburgh Castle's history.
The Royal Botanic Garden also holds an illuminated walking tour during the festive season.
The Castle of Light Consortium partners are War Productions Limited, Double Take Productions, NL Productions, and Andy McGregor.
Edinburgh Castle is Scotland's most popular paid visitor attraction. It is maintained by government heritage agency, Historic Scotland.
