Celebrating the city's multiculturalism, churches of four main local Christian denominations face each other on a small hill dissected by 18 Novembra iela. While local Lutherans flock into the red-brick neo-Gothic Martin Luther Cathedral, the Catholics congregate at Holy Virgin Cathedral. The above two mingle with the Russian Orthodox Cathedral of Princes Boris & Gleb and the Old Believer's Novostroyensky Church of Resurrection, Holy Virgin & St Nikola.
All except for the latter – Russian dissidents have always been a bit of a secret society – are open for visitors. See how blessed you can get in one go.
