Madrid can brag about having lots of parties that brighten up its streets, but few of them have such an impact on so many areas of Madrid as the arrival of Christmas. That’s why, from the end of November until Three Kings’ Day, streets, squares and buildings are lit up by millions of lamps that comply with the strictest environmental and energy efficiency requirements, giving off more light, but consuming less energy. Nor should we forget the traditional Christmas trees and nativity scenes that are set up in different areas of the city, not to mention all the different activities organised for the Christmas holidays, such as ice rinks or Christmas markets.
