The cathedral square,the spur of the Civita (old town), divides the two neighbourhoods and offers a wide view of the Church and of the Sasso Barisano. A bit further, on the right side of the Cathedral, going beyond the Arch of San Potito and along via Muro, one can see the Sasso Caveoso. From the square, thanks for the proximity of the two neighbourhoods, in few minutes you will perceive the change from the homogeneity and composure of the Sasso caveoso to the variety of the Sasso Barisano and of the Piano (old city at the ground floor level).
