There are a number of Christmas markets in Berlin which you may find interesting as they are less jingle bellsy and more unusual in terms of what they sell and how they are organised.
Holy Shit Shopping takes place on December 11-12 in two locations, Spandauerstrasse 2 and Karl Liebknechtstrasse 9-10. 12-7pm. You will find artists, designers and all sorts of other creatives selling their goods to the sound of DJs and live acts.
Trendmafia is an indoor market which will be on on the first three weekends in December (4/5, 11/12, and 18/19). 1pm -8pm. Location is the Underground station Bernauer Straße in Mitte. As the name implies this is a market for up and coming designers in fashion, jewellery, and home accessories.
Weihnachtsrodeo wants to be the coolest of all the markets. As it takes place on the last weekend before Christmas this can be your last minute chance to get your gift shopping done in a fun atmosphere. The location is HAUS UNGARN in Karl-Liebknechtstrasse 9.
Handmade Supermarket is another last chance market for your xmas shopping. On December 18-19 from noon to 8pm in Eisenbahnstrase 42 Berlin-Kreuzberg.
