The Apostolic Palace is the official residence of the Pope. The building contains the Papal Apartments, various offices of the Catholic Church and the Holy See, private and public chapels, Vatican Museums, and the Vatican Library, including the Sistine Chapel, Raphael Rooms, and Borgia Apartment. The modern tourist can see these last and other parts of the palace, but other parts, such as the Sala Regia and Cappella Paolina, are closed to tourists.
In the fifth century, Pope Symmachus built a papal palace close to the Old St. Peter's Basilica which served an alternative residence to the Lateran Palace. The construction of a second fortified palace was sponsored by Pope Eugene III and extensively modified under Pope Innocent III in the twelfth century.
Upon returning to Rome in 1377 after the interlude of the Avignon Papacy, which saw Rome subject to civil unrest and the abandonment of several Christian monuments, the popes chose to reside first at Basilica di Santa Maria in Trastevere and then at Basilica di Santa Maria Maggiore. The Vatican Palace had fallen into disrepair from lack of upkeep and the Lateran Palace underwent two destructive fires, in 1307 and 1361, which did irreparable harm. In 1447, Pope Nicholas V razed the ancient fortified palace of Eugene III to erect a new building, the current Apostolic Palace.
In the 15th century, the Palace was placed under the authority of a prefect. This position of Apostolic Prefect lasted from the 15th century till the 1800s, when the Papal States fell into economic difficulties. In 1884, when this post was reviewed in light of saving money, Pope Leo XIII created a committee to administer the palace.
Construction of the Papal Palace at the Vatican in Vatican City, took place mainly between 1471 and 1605. The major additions and decorations of the palace are the work of the following popes for 150 years. Construction of the current version of the palace began on 30 April 1589 under Pope Sixtus V and its various intrinsic parts were completed by later successors, Pope Urban VII, Pope Innocent XI and Pope Clement VIII. In the 20th century, Pope Pius XI built a monumental art gallery and museum entrance.
Perhaps the best known of the Palace chapels is the Sistine Chapel named in honor of Sixtus IV. It is famous for its decoration that was frescoed throughout by Renaissance artists including Michelangelo, Sandro Botticelli, Pietro Perugino, Pinturicchio, Domenico Ghirlandaio, and others.
One of the primary functions of the chapel is as a venue for the election of each successive Pope in a conclave of the College of Cardinals. In this closed-door election, the cardinals choose a successor to the first pope, St. Peter, who has traditionally set up residence within the Apostolic Palace.
This suite of rooms is famous for its frescos by a large team of artists working under Raphael. They were originally intended as a suite of apartments for Pope Julius II. He commissioned Raphael, then a relatively young artist from Urbino, and his studio in 1508 or 1509 to redecorate the existing interiors of the rooms entirely. It was possibly Julius' intent to outshine the apartments of his predecessor (and rival) Pope Alexander VI, as the Stanze are directly above Alexander's Borgia Apartments. They are on the third floor, overlooking the south side of the Belvedere Courtyard.
The Borgia Apartments is a suite of rooms in the Palace adapted for personal use by Pope Alexander VI (Rodrígo de Borgia). He commissioned the Italian painter Pinturicchio to lavishly decorate the apartments with frescoes.
The paintings and frescoes, which were executed between 1492 and 1494, drew on a complex iconographic program that used themes from medieval encyclopedias, adding an eschatological layer of meaning and celebrating the supposedly divine origins of the Borgias.
The Clementine Hall was established in the 16th century by Pope Clement VIII in honor of Pope Clement I, the third pope. Like other chapels and apartments in the Palace, the hall is notable for its large collection of frescos and other art.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
