Although, Riga Ghetto and Latvian Holocaust Museum is more of an outdoor monument with exhibits than a museum, this courtyard between streets of Maskavas and Krasta is still worth paying a visit to, especially if you are interested in some Jewish history.
Its main feature is an very long wall covered with the names of victims of the Holocaust period in Latvia. You can also look at Nazi propaganda, horrifying photos of tortured bodies, stills of ghetto life and grainy black and whites of old synagogues across the country, most of which does not exist anymore.
