On Pentecost Day, the 14th of May, 1606, Fr. Carafa celebrated the first Mass in the church of the Madonna of the Mountains. The memory of that day remains in the coat of arms of the Congregation which shows three mountains (one of which is above the other two) and the monogram of the Virgin (the letters M and A) surmounted by the Holy Spirit in the form of a dove. And so since then the Monday of Pentecost is celebrated as the feast of the Madonna dei Monti. To this day the tradition remains and vast numbers of the faithful come to the sanctuary on this day.
