 Each contains a Holy Door, opened only during official Jubilee years.Sanctuary of Our Lady of Divine Love was added by Pope John Paul II for the Great Jubilee of 2000, replacing St. Sebastian Outside-the-Walls.However, many pilgrims still prefer the pre-2000 seven basilicas and so also attend St. Sebastian's in addition to the ones required for the indulgence, or even instead of the Santuario (given that the walk from the Santuario to the Inner City takes at least a half-day just for itself, and that there is an indulgence for visiting any of the four major basilicas anyway).
