Latgalite, Corner of Gogola and Dzirnavu iela. If you are looking for Soviet era hats, medals, pins, or complete uniforms, go to this flea market. Also has a large selection of Soviet-era surplus electronics and miscellaneous household items. If it's your dream to own an oscilloscope from the Eastern Bloc, this is not a bad place to look. On the way there you will see old buildings that aren't exactly well conserved, but there are some that are breathtaking.
