The square of Marjorie is the main square of Bologna, built in 1200 AD, located in the center of the city, surrounded by several medieval buildings, the church on the picture is the famous St. Peterronio Cathedral (Basilica di San Petronio), This church, like the Great Gallery, is not known to many people, and looks so inconspicuous because it is an unfinished church. The original plan was to build more than St. Peter's Basilica, but after a hundred years of construction, the pope suddenly interrupted construction, only completed the church's nave, but it was large, the interior of the church is still one of the few churches in Italy.
