Ah everyone loves something for free and Berlin has quite a bit you can take advantage of.
If you are keen on art then head for Auguststrasse where a host of commercial galleries await your visit all year round.
Come the last week of April and there is the fantastic ´Gallery Weekend´ in Berlin. An annual event that sees around 50 leading galleries open their doors to the public for three days and three nights. At many of the openings the artists will be around to have a chat and you can typically enjoy a glass (or two) of wine and sometimes even snacks.
There is also a wealth of free entry museums in Berlin to suit every interest and timescale. Make sure you don’t miss out on these gems ranging from the Memorial and Museum Sachsenhausen, located on the former site of Sachsenhausen concentration camp, now open to the public as a museum and memorial to the er… Sugar Museum, a museum dedicated to sugar!
A number of companies offer free tours around the city including Sandeman and Alternative Berlin tours where you can see street art, squats and alternative Berlin.
