The main church of Bologna, San Petronio Basilica dominates the main plaza. Construction on the church began in the 14th century and was dedicated to a 5th century Bolognese saint. One of the most fascinating parts of the church is the elaborate sundial found inside. The sundial is in the form of a meridian line and was added in the 17th century. The famous astronomer Giovanni Domenico Cassini designed the sundial and its measurements are amazingly precise.
