What to do on Sunday in Bari. Of course you can work, but for sure you will need a break. We suggest you to take a walk in Bari Vecchia, where you can visit the basilic dedicated to the patron saint of Bari San-Nicola and there is also the Cathedral that is worth a visit.
Wherever you go in Italy, from the bars on the highway to beach cabins, you will find good coffee. However some places are really cathedrals for coffee, make good pastry, cookies, chocolate and also ice-cream. Just a small selection of places in the city center( near to your hotels) you can find here:
corner via Calefati with via Sparano
Inside the Petruzelli Opera house
If you would like to go a day out of the city, you can visit Polignano a Mare: a small town built on the rocks that face the Adriatic sea. There is a train every 2 hours on sunday and it takes about half an hour to reach the city.
