Riga has the largest concentration of Art Nouveau buildings in the world, several of which were designed by Mikhail Eisenstein, father of the famous Russian film director, Sergei Eisenstein. This stylized Greek warrior (designed by Eisenstein) is on the School of Economics at Streinieku iela 4.
Riga also has a beautiful medieval city center complete with requisite cobble-stone streets and gothic churches. It's easy to get to Riga by boat from Scandinavia or by plane on Air Baltic, which flies to Riga from many cities including Athens, London, Paris, and Rome. I can't wait to go back!
