Arcibasilica San Giovanni in Laterano
Dedicated to John the Baptist and John the Evangelist, the Basilica is also the cathedral of the Pope. Built in the 4th century by Constantine the Great, it is the very first church built in Rome. The main elements to see are the two-storied portico, the Cosmatesque pavement with the Colonna family’s coat-of-arms, the baldacchino, whose reliquary contains the heads of Saints Peter and Paul, the High Altar, the Altar of Holy Sacrament and the cloisters that represent the remains of the Benedictine monastery, Romanesque and Gothic style.
