The memorial site of a concentration camp where the Nazis murdered thousands of Jews and other ethnic groups, including Latvians, is outside of Riga city limits, but worth the trip. On the walls of a concrete structure, which now serves as the gateway to the camp, the words 'The earth moans beyond this gate' are inscribed. Half a dozen monumental statues symbolising hope and defiance are located here. A metronome eerily ticks in memory of the victims and the foundations of the barracks are still visible. Take bus No.18 from the Central Market to the last stop, Dārziņi-2, and then carefully walk across the motorway to the memorial.
