Here are some pics of a visit of the internal rooms of Palazzo Lateranense, a not so well-known but beautiful Palace near Basilica San Giovanni.
This palace has a number of large halls richly decorated with ancient frescoes and furniture. Pope Paolo VI has embellished the palace with a number of very large and beautiful tapestries.
