The Marburg B(u)y Night is a great event. All stores are open till midnight, their are great light…read moreeffects. Especially in the - after big streetwork - completly new Ketzerbach was very beautiful. Also the castle and the old part of downtown (Oberstadt) was very beautiful and crowded. So it's less the shopping event, but a sightseeing tour through Marburg, also if you live their already for a couple of years.
