The Lateran complex consists of several high interest sites: the Basilica, the Cloister and the Treasure Museum, the Baptistery and the Holy Stairs, which contain the casket of the Chapel of the Sancta Sanctorum. This special ticket allows you to easily access the complex and visit all the points of interest in around 2 hours with a multilingual audio-guide system. You will begin your visit by visiting the basilica with the cloister and the Treasure Museum, before then proceeding outside the church to the baptistery which is located in the square behind. During the second half of your tour, you will visit the building of the Holy Stairs, which is located on the right of the basilica, and admire the Chapel of the Sancta Sanctorum. If you only have one hour, you can visit the basilica and its cloister first, followed by the Holy Stairs and Sancta Sanctorum.
