Bologna's old city centre is ideal for walking as the arched walkways offer some respite from the heat of summer. This central piazza is full of life with many locals gathering to chat and pass the time, you can listen to musicians or watch the street performers from one of the many cafés or bars that surround the edges. These bars kick off long into the night as well. Or, you can just sit and admire the renaissance buildings and the sun reflecting off the ornate façades.
