Hey, I was in Prague last month. How did I miss an archaeological dig in the centre of the city? This article from Radio Prague gives some information about the dig, and quotes archaeologist Petr Jurina, who says:
"I would like to mention above all the find of potter's kilns from the fifteen and sixteen centuries. We have discovered about ten of them which is the most that has been found ever. Apart from that we also found a golden ring with a gemstone from the 12th century with a Hebrew epigraph ‘Moses the son of Solomon’."
"What is most important is that it changes our notion of the original inhabitation of Prague, especially the 12th century. It turned out that the Roman palaces were not only on the territory of the so called Old Town, but this housing continued northwards up to what is now Florenc. So we found Roman stone houses and palaces but apart form that we found out that there were also valuable wooden architecture." [continue]
