The Dome of St. Peter’s Basilica dominates the
skyline of Rome city. Indeed, while taking in Rome’s magnificent panorama, it
is hard to miss it. All for the better, for it is hard to imagine that anyone
would want to miss such a pretty sight.
The Dome of St. Peter’s Basilica is,
undoubtedly, one of the most impressive sights in Rome. Considering the amount
of breath-taking wonders that this eternal city can boast of, that is saying
something.
Recently I have finished a new oil painting that was inspired by St. Peter's Dome in Vacation. Hence today (besides sharing this new painting of mine), I would like to share some lesser know facts about Dome of Saint Peter. This masterpiece of architecture is certainly worth a study. So, here are ten interesting facts about the St. Peter’s Basilica
Dome.
Ten interesting facts about the St. Peter’s Basilica Dome
#FACT 1
1
Michelangelo is known as the designer of the
Dome and rightfully so, but he was hardly the only man who contributed to it. In fact, Michelangelo followed in the footsteps of Bramante and Sangallo.
Bramante was
the architect chosen for the job when Pope Julius decided to build the grandest
church in Christendom. Pope Julius set the stone for it in 1506. At the time,
there were only 3 large domes in existence. One of them was located in faraway
Constantinople (church Hagia Sofia) so the architects lacked the opportunity to
study it. However, the other two, Pantheon in immediate vicinity and the famous
Dome in Florence, were easily available for study. Bramante, as did the other architects,
studied both the Pantheon and the Dome of Florence. He had planned for the Dome
to be as wide as that of the doom Florence and even taller. While he was
studying the Pantheon, Bramante even learned to mix concrete in the way the
ancient Romans did it, so that it wouldn’t be too heavy. It is said that Bramante designed the Dome
with Pantheon with mind, but with the elements from Dome of Florence, for
example he added the little stone tower that would stand at the top of the Dome
and be called lantern. When Pope Julius died, Pope Leo X appointed three
architects to work on the Basilica: Guiliano da Sangallo, Fra Giocondo and
Raphael. After Raphael died, Sangallo made changes to Bramante’s design of the
Dome. Sangallo designed the Dome to be much stronger and made plans for the elaborative
decoration of the Dome but the most important thing that he did was to take
care of the piers that started to crack. Sangallo’s plans for the design of the
Dome were never put into action. In the end, it was up to Michelangelo to make
the great design.
#FACT 2
Michelangelo consulted the work of his
predecessors, but he made his own designs. When he decided to take upon himself to create
the Dome, Michelangelo sought to harmonize it with design of the Basilica.
Michelangelo
designed the Dome with two shells instead of one, because of the fact that a
high dome looks better from outside and the lower one from inside. This way he
was able to make the best of both worlds while also allowing a place for a gap
within the two. This gap is equipped with stairs that people could use to
repair the Dome. The same sense of aesthetic that guided Michelangelo work on
St. Peter’s Basilica can be seen in the Dome. It remains unclear whether
today’s Dome is exactly the way Michelangelo imagined it to be, but he is still
considered its main designer. It has often been noted that the Dome and the
church exist in perfect harmony. We can’t really blame Michelangelo for the
structural problem the Dome faced (and that was fortunately fixed in time)
because the Dome itself was a ground-breaking and pioneer work. It was a feet
of courage, creative and artistry. It is said that Michelangelo was mostly inspired
by Pantheon and the Dome of Florence. There were even rumours that bronze from
Pantheon was used in the construction of the Dome, which surely enough lead to
criticism.
# FACT 3
The Dome of St. Peter’s Basilica was
one of the latter works of Michelangelo, thus it enabled him to use of all of
his vast experience. He was 71 years old when he started working on the Dome
and he laboured on it until his death.
Unfortunately, Michelangelo died before
he could complete the Dome. When he died, the construction stopped at the drum
of the dome.
Eventually, the Dome was finished 26 years
later (in 1590) by Giacamo della Porta and Domenico Fortuna.
During his life, Michelangelo identified himself primarily as a sculptor. It is
said that his imagination of a sculptor was a defining influence on his
architectural works. He imagined buildings as clay that can be shaped. Supposedly,
he even found it difficult to work with the popes, but accepted the challenging
job mainly for religious reasons. Nevertheless, with both the St. Peter’s Basilica
and the Dome of St. Peter, Michelangelo proved that he was also an amazing
architect. Michelangelo had worked on
The Dome until the day he died, which proves how important it was to him. In many ways, it is only just that he is considered the mastermind behind the Dome.
#FACT 4
Michelangelo’s Dome wasn’t finished when he
died in year 1564. For a while, the work on it was suspended. It was in 1588 that energetic Pope Sixtus, who came to be
known as the first modern urbanist, appointed Giacamo della Porta and Domenico
Fortuna to finish the Dome.
Porta was
one of Michelangelo’s pupils. He did his best to fulfil the vision of his great
master, but he also insisted on making some changes in Michelangelo’s design. Porta
argued for the top of the Dome to be altered. His idea of vertically elliptical
profile was eventually accepted and it proved beneficial due to structural
reasons. Some argue that Michelangelo himself might have made this suggestion
before his death, but generally this change is attributed to Porta, who
supposedly had more scientific knowledge than Michelangelo.
To finish this important project, Giacamo della Porta also collaborated with
Domenico Fontana, another well-known Italian architect/engineer of this period
who is perhaps best known for his feat of erecting a 320 ton obelisk on the
Square of Saint Peter. The two of them managed
to see the construction of Dome through. Fontana and Porta made the changes
where changes were necessary, thus reducing the tensile stress in the Dome by
40 percent. The Dome was finally build up to the base of the lantern in 1590, a
few months prior to Pope Sixtus’ death. The
lantern and the lead covering were completed later. The Dome didn’t achieved
its signature look until the cross was put on it in 1592.
# FACT 5
There was one major crisis in the life of Dome.
Because of its enormous size, it faced the risk of falling down.
Interestingly,
this beautiful symbol of Rome was, at one point, seriously endangered. The Dome
was designed beautifully, but the design lacked precision and expertise that
today’s technology enables. Back then, there were no programs that architects
could use to calculate the risk and prevent cracks. In other words, the Dome nearly
collapsed due to structural problems. In fact, by the eighteen century a crack
had been discovered. Pope Benedict XIV consulted numerous experts, but it was
not until he found the right man that the problem was solved. The man who saved
the Dome from collapsing was a Croatian Jesuit, polymath and mathematician
Roger Joseph Boskovich. This known scholar, who according to many pathed the
way for the theory of atom, solved many construction problems during his life.
Fortunately, Boskovich was also able to foresee to the structural problem of
Saint Peter’s Dome. In 1742, Roger Joseph Boskovich was consulted on the
matter. He suggested placing five concentric iron bands to support its
structure. Pope Benedict XVI accepted Boskovich’s preposition. Thus, the Dome
of St. Peter’s Basilica was saved.
#FACT 6
The Dome’s size is impressive even for today’s
standards. The top of the Dome is a staggering 448.1 feet (136 meters) tall.
Interestingly enough, Saint Peter’s Dome still holds the title of the tallest
Dome in the world.
The Dome’s internal diameter is equally impressive- 136. 1 feet (41.47 m). Even
today, the Dome is one of the largest in the world. At the time of its
completion, it was the largest Dome in the world. Its diameter is only slightly
smaller of the Pantheon, on whom it was supposedly modelled. The Dome is beautifully
decorated. The two inscriptions on the Dome are easily read because they are written
in letters that are 6.6 feet (2 meters) tall. These inscriptions, written in Latin, state
the following: ‘You are Peter and on this rock I will build my church….I will
give you the keys of Heaven….’ None the less magnificent is the church within which
the Dome is placed, that is Saint Peter’s Basilica, considered by many to be
the greatest church in Christianity. Protected by UNESCO and regarded as a
masterpiece of Renaissance architecture, one could add that St. Peter’s
Basilica seems more than worthy of such a glorious Dome. Together they make for
a perfect pairing. Covering 2.3 hectares (5.7 acres) St. Peter’s Basilica is
certainly one of the largest Christian churches, if not the largest. None
withstanding its size, the Dome is said to dominate the church, both internally
and externally.
The Dome, together with the Basilica itself,
meet with heavy criticism because of its huge expense.
As it is easy to imagine, a lot of money was needed to build such architectural wonders. One of
the methods employed for collecting the money needed for construction was the
infamous ‘granting of indulgences’. To say that the financing of construction
of Basilica and the Dome gave rise to rebellion that in turned lead to Protestantism
would perhaps be pushing it too far, yet it was one of the factors. Moreover,
it is certain that the practice of ‘granting indulgences’ used for financing
the Basilica and its Dome was one of the things that inspired Martin’s Luther
rebellion.
This Dome was used as a model for other Western
domes in the world. It could even be said that it set standard for domes
worldwide.
It is said to have inspired numerous domes, including that of Les Invalides
in Paris. Thomas U. Walter, the architect that designed the Dome for the
Capitol building, is said to have been inspired by the Dome he saw when he
visited Les Invalides in Paris. Consequently, it can be said that the Dome of the
Capitol building in Washington follows in the tradition of Dome of Saint Peter.
What is certain is that St. Peter’s Dome was and remains an architectural
wonder. There
was one major crisis in the life of Dome. Because of its enormous size, it
faced the risk of falling down. Interestingly, this beautiful symbol of Rome
was, at one point, seriously endangered. The Dome was designed beautifully, but
the design lacked precision and expertise that today’s technology enables. Back
then, there were no programs that architects could use to calculate the risk
and prevent cracks. In other words, the Dome nearly collapsed due to structural
problems. In fact, by the eighteen century a crack had been discovered. Pope
Benedict XIV consulted numerous experts, but it was not until he found the
right man that the problem was solved. The man who saved the Dome from

Boskovich. This known scholar, who according to many pathed the way for the
theory of atom, solved many construction problems during his life. Fortunately,

Dome. In 1742, Roger Joseph Boskovich was consulted on the matter. He suggested
placing five concentric iron bands to support its structure. Pope Benedict XVI
accepted Boskovich’s preposition. Thus, the Dome of St. Peter’s Basilica was
saved.
# FACT 9
One of the most fascinating way to observe the
Dome is to experience the optical illusion at Via Niccolo Piccolomini.
If you choose to visit this street you can
experience the optical illusion of the Doom appearing closer as you move away
from it and vice versa. Equally interesting is the view of Dome through one
keyhole. If you want to see the Dome through the keyhole all you have to do is
visit Villa Del Priorato di Malta and peep through that keyhole. Besides, that
famous keyhole view, this Villa offers an enchanting view of the city.
Additionally, you can enjoy a stroll in the beautiful garden the Villa is
famous for.
If you want to visit the Dome itself, you'll have to climb a lot of stairs (or get someone to carry you all the way).
As it was explained in this article, St. Peter's Dome can be seen and experienced in many ways. Nevertheless, to get a precise feel of it, perhaps it is the best to visit this Dome itself. The Dome is open to all visitors on daily basis. So, in case
you’re not content with seeing it from afar or even with glazing at it from directly
under (once you find yourself within Saint Peter’s Basilica), you can always walk all the way to the top and get a detailed view of its beauty. There are 491 (narrow)
stairs leading to the top, so it is a long climb, but the experience is said to
be well worth the climb. There is also a small fee that needs to be paid if you
want to climb those stairs, so be sure to bring some change.
