It is walkable, and I recommend you do it, at least once you get to the Viale Italia onwards. Hop off the bus at the Cantiere Navale (Piazzale Orlando) and walk the rest of the way to the Terrazza, it's a really nice promenade.

per queste domande c'è wikipedia.....!

Hi Fitover50, It's depend where do you came from. Generally you can choose a Shuttle or a Taxi to get the center city. It's not possible by foot. The Cathedral is in P.zza Grande. I would suggest some small churches to visit that represent the soul of the multicultural city of Livorno. The Church of Our Lady in Via della Madonna is the church where all religious denominations in the city had an altar where to pray. E 'can still see the altar of the English of the French Armenian etc .... if you ask the pastor you can also see a kiosk medieval accessed from inside the church. Another visit is worth the Church of St. Catherine in the square of the Dominicans in the Venice neighborhood. If you can still advise you to refer to an experienced guide, and see a city with a unique history and wonderful.
