Wikipedia: "Adjoining the Cathedral are the Parroquia del Sagrario (one of the oldest ones in Lima) and the Archbishop's Palace.
Inside, along the side aisles, are a sequence of large paintings of the Via Crucis, "Way of the Cross. Pope John Paul II visited this cathedral on two occasions, in 1985 and 1988. This is commemorated with signs at the entrance. In the left aisle, the first chapel holds the ancient baptistery. Here can be seen a beautiful image of Nuestra Señora de la Esperanza, who presides over the events during Cuaresm and Holy Week. During a recent restoration, ancient pictures were found in this chapel that are now able to be seen by the public."
