The present altar was built in 1747 by Ferdinando Fuga using four columns from the fifteenth century. The gilded bronze palm branches encircling the columns were added by Giuseppe Valadier in 1823. The columns have Corinthian capitals and Pope Benedict XIV's coat of arms at the base. The urn below the altar has the relics of the Apostle Mathew, St. Stephen, St. Lawrence, and other martyrs.

In front and slightly below the main altar is the confession, which Pope Pius IX had enlarged by Virginio Vespignani. The relic of Christ's manger is located above the lower altar in this area. At the back of the confessional area is a statue of Pope Pius IV by Ercole Ferrata, kneeling in prayer.

With the rise of nationalism and the formation of the Italian government, the Popes lived strictly inside the Vatican. From 20 September 20, 1870 until the signing of the Lateran Treaty on February 11, 1929 Popes did not leave the Vatican, not wanting to give any appearance of accepting the authority of the Italian government. They would not appear at Saint Peter's Square or on the balcony of St. Peter's Basilica facing the area. So, where did they go when the self-imposed isolation ended? You guessed it, Pope Pius XI's first visit outside the Vatican in 1929 was to St. Mary Major.
