Castle of Light returns for a second year after a pandemic break. 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 long-time 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 and storytelling to delve into Edinburgh Castle's history.
Rex, the lion rampant, will be there to guide families and unravel the mysteries of the castle, including background to The Honours of Scotland (also known as the Crown Jewels).
Castle of Light 2021 is set to be bigger than before, with bespoke video content, brand new installations and more than double the lighting.
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.
Timed entry from 4.30pm to 8.30pm. Event closes at 10pm. It is suggested that you allow around 90 minutes to fully experience the show but you can take as much or as little time as you like.

The event will also take place on select dates between Christmas and New Year - Monday 27, Tuesday 28, Wednesday 29, Thursday 30 December.
