visiting Lucca on a day trip, which one of these palaces would ypu recommend? Staying in Florence, I am not that interested in art, more in seeing beautiful buildings and interiors. Mansi is gorgeus, but most of it is art gallery, isn'it it? Pfanner has a lovely garden that is interesting.
Also planning on doing le mure di lucca, torre guinici, piazza anfiteatro and some of the churches, what else would you recomend?
