First, listen to the history of the catacombs: from their origin to their decline, and their rediscovery in the modern era. You will also learn how they were dug and administrated. Going down, you will enter the crypt of the Popes of the 3rd century, where 5 of the 9 tombstones of the bishops of Rome who were buried here are still preserved. You will then admire a wonderful slab of marble where some famous verses of Pope Damasus were engraved. Next, cross a narrow arch and enter the crypt where St. Cecilia, the patron saint of music was initially buried. The guide will tell you her inspirational history while you will contemplate the frescoes that decorate the crypt and a precious copy of the statue made by Maderno, depicting the body of the martyr when a reconnaissance was made in 1599. From the crypt of Santa Cecilia, you will continue your tour  through the oldest part of the catacomb, admiring its majestic galleries and the beautiful cubicles of "sacraments". Finally, you will walk through the maze of tunnels dug in peacetime, trying to find your way out. Along the way, you will be able to see various archaeological finds of funeral furniture before coming up to see the sunlight again.
