Upon nine years of excavations archeologists have found a triangle fortress foundation of flamed bricks and a jurt-shaped house by the Caspian Sea.
      
      Scientists assume these are remains of the ancient city of Atil, also spelled Itil (literally meaning "Big River"), which was the capital of Khazaria.
      
      Flamed bricks were used only in Atil located at the crossroads of great trade routes, the archeologists point out. The city location is described in middle-age chronicles of Arabic, Jewish, and European authors.
      
      The Khazars, one of the Turkic tribes, conquered a huge part of Russia, Ukraine, Caucasus and Central Asia. More than a thousand years ago they adopted Judaism, yet after their vanishing they left few traces of their culture.
