"Founded in 2004 by a local events agency, the Festival of Lights is now one of the city’s most popular events and one of the largest of its kind in the world. The concept is startlingly simple but effective: Every October, a slew of iconic sights — including the Brandenburg Gate, the TV Tower on Alexanderplatz, the Berliner Dom (Cathedral), and the Gendarmenmarkt — are transformed into a sea of color and light via creative projections, 3D artworks, and installations. There are associated art and cultural events throughout the festival, too, and even an annual photo competition open to the public.When: October" - MATADOR_NETWORK
