Turkey

In 1873, while excavating a hill in north-western Anatolia, the German archeologist Heinrich Schliemann [1822-1890] discovered a cache of treasure from ancient Homeric Troy; authenticity continues to be debated. Image source here.

Schliemann had his Troy discoveries appraised by Carlo Giuliano [1831-1895], who was Queen Victoria's [1819-1901] favored jeweler.
