Mater et caput of all Rome’s and the world’s Catholic churches, San Giovanni in Laterano is the oldest church of the Western World, founded in the 4th century by Constantine the Great. Dedicated to John the Baptist and John the Evangelist, it stands on the piazza by the same name, within Rome’s city center. San Giovanni in Laterano is also the city’s cathedral.
The basilica was reconstructed a few times until the 18th century, when the monumental façade, a two-storied portico supported by giant columns, crowned by 15 seven-meter-high statues, was redesigned. The solemn interior features a five-aisle nave, remodeled by Francesco Borromini in the 17th century, who also created the niches that would house the 12 colossal statues depicting the apostles. The graceful 14th century baldacchino over the high altar, which only the Pope can use, is surmounted by a reliquary said to contain the heads of Saints Peter and Paul. The Altar of the Holy Sacrament contains a cedar table said to be the one used by Christ during the Last Supper. A masterpiece of Cosmatesque art is the cloister.
Near the basilica, you can find the Scala Sancta, or Holy Stairs: white marble steps encased in wooden ones, which, according to Catholic tradition, once led to the praetorium of Pontius Pilate in Jerusalem on which Jesus Christ stepped on his way to trial during the events known as the Passion.
