Both evenings in Lucca we walked along the wall with our gelatos.  It is where many of the residents can be found exercising as well. We climbed Torre delle Ore and did some shopping- probably the best place for shopping on this trip.  The old amphitheater has been "repurposed" as a public square, with apartments in the old walls and many shops around the base. We ate one meal inside the amphitheater and enjoyed the lively dinner-time atmosphere there.
