Palazzo Laterano

Lonely Planet review

Flanking Piazza San Giovanni in Laterano, itself dominated by Rome’s oldest and tallest obelisk , is Domenico Fontana’s 16th-century Palazzo Laterano. Part of the original 4th-century complex of the Basilica di San Giovanni, it was the official papal residence until the papacy moved to the Vatican in 1377, and today houses offices of the diocese of Rome.
