How has your city prepared for the holidays? By throwing up a few thinning acrylic wreaths? By slapping on a few dreidel decals? Well, that’s not how they roll in Madrid. Each year, the city spends millions on decorations, which range from a 300-square-foot nativity scene to dozens of light shows commissioned by artists and designers who work in the city. This year, architect Teresa Sapey gives Madrid a mod makeover with hundreds of LED-lit Circles.
