Memorial to Europe's Sinti and Roma Murdered Under Nazism

Opened in 2012 after decades of advocacy, this memorial by Israeli artist Dani Karavan takes the form of a dark circular pool with a single fresh flower placed at its center each day, ringed by stones engraved with the names of concentration camps where Sinti and Roma were murdered. A recorded violin piece plays intermittently, and an accompanying video installation and information panels provide historical context that many visitors say fills a real gap, since this chapter of the Holocaust receives far less attention than others.

Set in a small park just steps from the Reichstag and Brandenburg Gate, it's easy to miss but, as reviewers note, well worth the short detour. Its low profile relative to its high culture score suggests it rewards those who seek it out rather than stumble past it.
