San Giovanni in Laterano, officially known as the Archbasilica of Saint John Lateran, is one of the four major basilicas of Rome and holds the title of the cathedral of the Diocese of Rome, making it the Pope's ecclesiastical seat. Founded in the fourth century, it was the first Christian basilica built in the city and has undergone numerous renovations over the centuries, reflecting various architectural styles, particularly Baroque and Neoclassical. The basilica houses significant artworks, including sculptures and frescoes, and is home to the famous Scala Santa, a set of steps believed to be the same ones that Jesus ascended during his trial before Pontius Pilate. Guided tours offer visitors insights into its rich history, art, and the important role it has played in the development of Christianity.
