The Sacred Military Constantinian Order of St. George is run by the Grand Master, helped by the Royal Delegation, formed by the most important people: Grand Prefect, Grand Prior, Grand Inquisitor, Grand Chancellor and Grand Treasurer, the President, the Vice President, the Secretary, and present Deputies.
Its present Grand Master, His Royal Highness Prince Ferdinand of Bourbon Two Sicilies, Duke of Castro and Head of the Royal House, is also helped by a Magisterial Juridical Council and by a Counsellor for Dynastic Orders and Orders of Knighthood.

The Grand Master is life-administrator of the Order and can promulgate new laws and statutes as well as appoint the highest institutional positions to which he will give the moral, disciplinary and administrative rule of the Order.
The position of Grand Prefect is held by HRH Charles of Bourbon Two Sicilies, Duke di Calabria, heir of the Duke of Castro.

The Knights and Ladies are divided into four Categories: Justice, Special, Grace and Merit. The Order is structured with Delegations and territorial deputations in many countries of the world and has Delegations also in every Italian region.
Many ecclesiastic personalities are members of the Order and guarantee the pursuit of Christian values and service to the Catholic Church, as established in the Statutes. The most important ecclesiastic representative is the Grand Prior: presently S.E. Cardinal Mario F. Pompedda holds this position.

The seat of the Grand Magistery is at the Grand Master’s residence whereas the seat of the Grand Chancellery is in Naples and the Secretariat of the Order is located in Rome, 121 Via Sistina.

A special symbolic importance is given to the decoration of the Order: a Greek Cross of 50 mm, with four lilied and golden hedged limbs, enamelled in purple colour and bearing the letters ISHV at their four edges and the XP monogram in the middle, between the Greek letters A and . The Cross is topped by a golden Royal Crown hanging from a golden Arms Trophy with flags, cannons, arrows, quiver, halberds, drums and crossed swords that support the armour crowned by a plumed helm. A golden image of a mounted St. George killing the dragon hangs down from the Cross.

The ribbon of the Order is in blue silk.

The use of insignia on the Italian territory is authorised by Decree of the President of the Republic; it is now the concern of the Minister of Foreign Affairs of the Republic.
