Bau, the trade fair that is staged in Munich every two years, is to be relaunched in 2011 as the "world's leading fair for architecture, materials and systems". This reflects a repositioning of the fair away from the current focus on Europe to become a trade event with claims to world leadership in its field. The Bau fair staged in January of this year registered a new record total of 212 000 visitors from 151 countries despite the economic crisis. In 2011 the fair will be held from 17 - 22 January, which is a week later than previously.
