The Roman Curia
The Roman Curia is considered to be where the Pope is, with the Chancery, Tribunals, and officials whom he employs in the Government of the Catholic Church.
In exercising supreme, full, and immediate power in the universal Church, the Roman pontiff makes use of the departments of the Roman Curia which, therefore, perform their duties in his name and with his authority for the good of the churches and in the service of the sacred pastors. CHRISTUS DOMINUS, 9. 
The Roman Curia includes the Secretariat of State, nine Congregations, three Tribunals, 11 Pontifical Councils, and other main offices.
One of the major Curial institutions is the Congregation for the Doctrine of the Faith, which oversees Catholic church doctrine.
The papal garrison
The visitors to Rome, who pose for a photograph in front of the Swiss soldiers on guard at the gates of Vatican City, are familiar with the history of these troops who take an oath of loyalty to the Pope. The Swiss Guards' official date of birth is January 22, 1506.
Every day they are engaged in mounting guard at the entrances to the Apostolic Palace and in the Sistine Chapel. However, the most important meeting is the one which takes place in the Vatican every year on May 6, on the occasion of the "Swearing in" of the new recruits.
