In an area in front of Sofia's Saint Alexander Nevsky Cathedral there is a daily flea market. It is quite a sight to behold.
Over the years I have become a devout attendee and shopper. Religious icons. Greek, Roman and Byzantine coins -- some real, some fake. Relics from the two world wars. If one looks closely, there certainly are a tremendous amount of left overs from a specific German u-boat. Fakes? Old cameras. Long forgotten utensils. And then there are Warsaw Pact era memorabilia. Uniforms, hats, medals, binoculars. Miniature bronze busts of Lenin, Stalin.
Fascinating, but buyer beware -- that must have been one large u-boat, with so much memorabilia left behind. In landlocked Sofia.
