In mid-November, the medieval cathedral of Burgos in northern Spain was lit from within–not by any divine power, but by the miracle of technology. For her temporary light installation “Chromotopia Santa María,” (November 3-13, 2016) Vienna-based artist Victoria Coeln used projected rays of light in brilliant colors to fill the ample space of the cathedral, the white limestone walls intensifying the vivid colors. It’s as if the cathedral’s stained glass windows had turned themselves inside out, dissolving the solid stone structure into layers of light.
