This little, inconspicuous house, painted white, doesn't actually belong here. And yet it is there, in the middle of Berlin's district Wedding. The artist Ryan Mendoza has brought it from Detroit to Berlin. Threatened by demolition, it represents an important part of American history. At the end of the 1950s, the African-American civil rights activist Rosa Parks lived in this house. When the bus driver demanded her place, she remained seated. The action cost Rosa Park's job and home. But it inspired Martin Luther King and touched off a civil right movement.
