As the holiday season is getting closer, cities light up their streets and open their Christmas markets. This custom finds its roots in Middle Age Germany and is becoming ever more popular in many cities worldwide. During the 4 weeks of the advent, the period preceding Christmas day, Christmas markets are sprouting around the globe. These ephemeral islands of Christmas magic are enlivening the cities with scents of roasted nuts, bratwurst and mulled wine. The accent is set on artisanal, hand-made products as well as traditional ornaments and gifts from around the world.
