Last night was 'Culture Night' in Gothenburg. all museums had free entrance and there were many public performances going on in different places, being performed by people of many countries, including Sweden of course. The library was also busy with films being shown in their auditorium, and them selling their old books and magazines for 10 - 20 Kr. Their were music being performed inside the library as well!
