From its most ancient origins, it has been dedicated to the glorification of the Cross, the propagation of the Faith, and the defense of the Holy Roman Apostolic Church, to which it is closely bound by special merits and by numerous marks of recognition and benevolence granted by the Supreme Pontiffs.

In keeping with the needs of the times, the Order is devoted to supporting two major works of social importance: Hospital Assistance and Charity.

Jubilee Pilgrimage of the Sacred Military Constantinian Order of Saint George
Saturday, 25 October 2025

On the occasion of the Ordinary Jubilee Year, H.R.H. Prince Carlo of Bourbon Two Sicilies, Duke of Castro, Head of the Royal House and Grand Master of the Dynastic Orders, has decided, together with His Most Reverend Eminence the Cardinal Grand Prior and the other Grand Charges, to organize an International Pilgrimage of the Order titled “Spiritu Ambulemus” (Let Us Walk in the Spirit).

The goal of the Pilgrimage is to reaffirm the Orders’s spirit of service by supporting on this occasion, the Case Famiglia Project of the Circolo San Pietro. The Circolo provides two residential facilities for families of underprivileged children, both from Italy and abroad, who are long-term patients at the Bambino Gesù Pediatric Hospital. These facilities offer furnished rooms, each with a private bathroom, and access to a kitchen for families to prepare their own meals.
