I agree with Nan that Lecce with its Barocco is unique and the entire town with maybe 30 or 40 churches, baroque palaces and gates deserves to be included to the WHS list. In the proposal, there are only 5 churches/buildings included: basilica di Santa Croce (main facade under scafoldings now, but it is really a gem of Meditteraen Barocco), S Giovanni Battista (the main facade under scafoldings now), Santa Chiara, Piazza del Duomo (the ensamble is so delicate!), and SS Nicolo e Cataldo (I spent 3 days in Lecce but could not see this becase it is outside the town walls and I have not noticed that this complex is also listed in TWHS nomination...). I do not understand why only these churches were selected in Lecce, because I could read the studies that positions of main facades, shape of piazzas, direction of main streets, and possition of main monuments such as Campanile del Duomo or Colonna S Oronzo or Porta Rudiae have been carefully planned by baroque masters. It is also strange to me why the Title of the nomination is "Salento and the "Barocco Leccese"" even if the site is mostly about Barocco and not about Salento region.
I also visited Gallipoli with its cathedral, which is fully comparable to churches in Lecce but it has huge oil paintings covering the walls instead of usual frescoes.
I have no time to visit other sites, because I travelled by train and it has its own specifics in southern Italy...
In conclusion, Lecce is simply great, and I must return to Lecce to see repaired facades of S Croce and S Giovanni Battista.
