Berlin Travel Stories - Lonely Planet
Top free things to do in Berlin! Stroll the East Side gallery. A colourful memorial to freedom, the East Side Gallery sits along the Spree River and is the longest remaining section of the Berlin Wall. In the wake of the declassification of the wall, more than 100 artists from all over the world made their mark, turning it into an open-air gallery covered in declarations of peace and other politically minded murals and graffiti.
