At 1316 metres long, the open-air art gallery on the banks of the river Spree in Friedrichshain is the longest continuous section of the Berlin Wall still in existence. Immediately after the wall came down, 118 artists from 21 countries began painting the stretch of stones and concrete, and it officially opened as a gallery in 1990. We love to just take a stroll alongside the Wall to discover the art since each painting is an expression of hope for change. No wonder East Side Gallery is considered an international memorial to peace. In 2009 the Gallery was renovated and today the site is under the care of the city council and historic preservation of Berlin. This is a must-see in our opinion.
