The "Basilica of Saint Ambrogio" is close to the center of Milan. St Ambrogio is one of the most beloved churches by the people of Milan: it was originally built in 4th century but large implementations have been done from the 9th till the 12th  century. The 360 photo was taken just after the sunset and shows the atrium of the Archbishop Ansperto and the nartex, both built in 12th century: the nartex is the structure with arches that stays before the facade.
