In 2012, Berlin celebrated its 775th anniversary. Among the many festivities, several large open-air exhibits were constructed, including a beautiful walkable map of Berlin called City of Diversity in front of the largest church in the city. Though it's no longer on display, many visitors shared photographs of the exhibit on Instagram!
