Visit Berlin on a budget

Tourists walk beside restored segments of East Side Gallery, the largest remaining part of the former Berlin Wall, in Berlin October 30, 2009. A 1,300 metres (4,265 ft) stretch of wall, the world's longest open-air art gallery, was decorated by 118 artists from 21 countries in 1990, but has since been damaged by the weather, exhaust fumes, vandals, and souvenir-seeking tourists. The restoration work is expected to be completed in time for the 20-year anniversary in November of the fall of the wall which once divided communist East Berlin from capitalist west Berlin.
