BOREALIS, a mesmerising installation of light and sound, will bring the experience of an aurora borealis to Dublin Castle’s Upper Courtyard every night during Bram Stoker Festival 2022, from Friday 28th October until Monday 31st October. 

An artwork by internationally renowned Swiss artist Dan Acher, BOREALIS has wowed hundreds of thousands of people across the globe.  Its lush visuals and soundscape utterly transforms the sky above your head and time seems to slow down as you gaze at the mesmerising lights in a breath-taking experience of true awe and wonder. 

Throughout the ages, humankind has been enchanted by this natural phenomenon in the night sky; in some cultures, these flickering, dancing lights were seen as a sign of impending doom; in others, they were thought to be ancient ancestors communicating with their living descendants. Indeed, Stoker references dark clouds, strange weather and unexplainable lights in the sky to foreshadow the doom and destruction unleashed by Dracula in Whitby and beyond. 

Combining a tranquil soundtrack with colourful, moving light beams in a blend of technology and art, Borealis inspires shared emotions in the centre of a city by creating something truly magical and surprising – something that shouldn’t naturally be there – and creates a sense of community by bringing together people from all walks of life for this truly unique experience.

This spectacular immersive installation, inspired by the Northern Lights, will take place in the Upper Courtyard in Dublin Castle where Bram Stoker once worked. 

BOREALIS is kindly supported by The Office of Public Works which manages Dublin Castle.

Borealis has been by enjoyed hundreds of thousands of people worldwide; from London to Tokyo, Paris to Adelaide, people have gathered to experience this truly magical event. Our fascination with the Northern and Southern Lights is not new; for our our ancestors, they inspired awe and astonishment.  By recreating their majesty in urban skies, BOREALIS brings city-dwellers together for an other-worldly experience under one strange and beautiful sky. Hear what people had to say about BOREALIS in London earlier this year:



An Aurora’s dancing lights are formed when the sun’s electrically charged particles enter the earth’s atmosphere, colliding above the magnetic poles. This is known as the Aurora Borealis in the North and the Aurora Australis in the South. This spectacular solar phenomenon is one of nature’s greatest wonders, creating ethereal lights in a range of colours that dance and swirl across the night sky. 

For centuries, people have looked up in awe at this strange, majestic and beautiful sight, creating stories and legends about its importance and meaning. 

  • It’s rare for the Northern Lights to appear over Southern Europe and such appearances require intense solar activity which usually results in red Auroras appearing in the night sky… until fairly recently, they were enough to terrify a populace unaware of the Aurora’s origin.
  • Residents of France and Italy believed the lights to be a bad omen heralding the outbreak of anything from war to plague and death.
  • In Scotland and England, the skies are said to have blazed red just a few weeks prior to the French Revolution and were later considered to have been a sign of the coming strife in their Gallic neighbour state.
  • Inuits of Greenland imagined the souls of dead children playing in the sky. The auroras have always commanded respect among people in the north, and in times past, a good dose of fear as well.
  • The aurora has long been seen as a harbinger of doom, perhaps because of its red, blood-like glow, in old tales in Poland, Prussia, Germany, Denmark, and Estonia, and among the Saami or Lapp people.
