Wroclaw - River Odra or Oder

We've barely had a chance to look around Wroclaw, what with being in a conference all day, not to mention the snow, and now we are off again tomorrow morning. But this certainly looks like a hidden gem, as the tourist websites seem to indicate. We hope to have just enough time for a quick trip around some of the sights tomorrow morning before getting the taxi to the airport, but it won't be long enough. So we must come back, I think.
