rivalling Versailles and continued an Italian tradition of majestic water gardens.

Next we encounter some of Italy's ties to the Second World War, from the seaside town

of Anzio to an abbey in the mountains of Cassino.

Following the trail of the ancient Appian Way, we then enter Rome for an aerial excursion

over its ancient ruins and its awe-inspiring architecture, including the Colosseum, the

Forum, the piazza Navora and the Palatine Hill.

From one of the most ancient cities in the world to the most holy, we visit the sacred

grounds of Vatican City.

We conclude our adventure in the hills of Tivoli with two palatial garden estates.

Our excursion to the magnificent Caserta Palace, constructed by Charles III in the mid-18th

century, begins by exploring the 4 kilometre-long garden which stretches up to the hillside.

The park was designed by Caserta architect Luigi Vantivelli and completed by his son,

Carlo, in 1780.

Comprised of a system of Baroque water features, the centrepiece is the Fountain of Aeolus.

An enormous promenade that spans the entire 120 hectare estate.

Adjacent and towards the upper end is the English Garden, designed in 1782 in the English

style, a reaction to the formal Italianate gardens of the time.

We cover the last segments of the Park as it ascends from the Fountain of Venus to its

terminus at the Great Fountain atop of the promenade.

An aqueduct was built to bring water to this grotto, from where it then begins its journey

down the hillside.

The aqueduct is 38-kilometres long and runs through five mountains, keeping the waterfalls

and other features fully operational.

The water first cascades 150 meters into the ornate basin of the Great Fountain.

Here, we find famous sculptures in the form of the Fountains of Diana and, to the left,

Actaeon, which depicts the hero transformed into a stag as wolves prepare to tear him

to pieces, a penalty for gazing at Diana as she bathed.

King Charles III wanted an estate to rival Versailles and Madrid's Royal Palace. Although

he never resided at Caserta, the result of his vision was what the World Heritage Centre

deemed the "swan song of the spectacular art of the Baroque".

Caserta provided assembly for its king, the court and the government. The 1200-room palace

is rectangular with four inner courtyards covering 3800 square metres.

We travel North up the coast to the fishing town of Anzio.

Situated on the Lazio coast, the port was a vital landing spot for an attack by Allied

forces in World War II.

The plan was to drive through to Rome, just 56km to the north, to liberate it from German

forces.

The ensuing battle left Anzio in ruins.

However, after the war much of the town was rebuilt, and in such a way that kept its fishing

town character.

And set back from the coast in the nearby town of Nettuno is a poignant reminder of

the scale of fighting that took place from 1943 to 1944.

This is the Sicily-Rome American Cemetery.

Rich in art, architecture and landscaping, this vast World War II memorial covers over

30 hectares.

Nearly 7900 fallen American troops are buried here amongst the rows of Roman pines.

Most of the casualties were sustained during the liberation of Sicily in 1943, while other

soldiers died in the landings of Salerno and Anzio and the heavy fighting northward.

We continue on to Cassino, at the southern end of the Lazio region.

And it's here we catch the dramatic sight of Monte Cassino Abbey.

Since its inception in the 6th century, it has suffered terrible fortune, repeatedly

attacked, pillaged or ruined by natural disaster.

During World War II the German forces used it as a stronghold, blocking access to Rome.

American led air-raids almost completely destroyed it in 1944 during the Allied forces' Italian

campaign.

The abbey, originally built by St. Benedict in 529, was reconstructed after the war in

its ancient architectural form, and finally re-consecrated by Pope Paul VI in 1964. With

relics from St. Benedict and St. Scholastica, tourists flock to the working monastery to

indulge themselves in its historical importance and its attractive architecture.

Our journey now takes us to the town of Frascati, where we encounter a magnificent exhibition

of Papal extravagance...

Villa Aldobrandini.

Set facing Rome, 20 kilometres away, this dramatic building was an ostentatious display

of the church's power and authority.

In 1600, Pope Clement VIII, a member of the Aldobrandini family, acquired this site, gifting

the property to his nephew, a cardinal.

The highly ornate villa and grounds were constructed during the Baroque period, at a time when

Popes attempted to outdo their predecessors with shows of grandeur, building palaces which

reflected their wealth and power. This estate served a ceremonial function for the Aldobrandinis

and was not used as a family residence.

During the second World War, there was significant damage to the Villa after bombing destroyed

over half of the town.

Today it remains an architectural treasure for its historical and cultural significance.

The Appian Way was once the most strategic road of ancient Rome.

It's also the site of the crucifixion of the gladiator Spartacus whose slave uprising ended

along this route.

It leads us to the eternal city and capital of the ancient empire—Rome.

During his journey to Italy, German novelist Johann Wolfgang von Goethe wrote that "only

in Rome is it possible to understand Rome."

We're now over the heart of the Italian capital and the River Tiber - winding through the

city that has influenced the world politically and socially for 2500 years.

And it's importance lives on to this day as the spiritual centre for the world's billion

or so catholics.

The splendour of Rome's ancient treasures can be seen almost everywhere.

From the imposing Trajan's Column, to the temples of the Republican period dating back

over two millennia.

They nestle effortlessly amongst newer landmarks, such as the Victor Emmanuel Monument.

One of the best preserved structures is the mighty Pantheon, the former temple to all

the Gods of ancient Rome.

And nearby is Piazza Navona, arguably Rome's most beautiful square.

Once a fortified city, the original walls can still be seen today.

They date back to the third century, erected around the seven hills of Rome to protect

against German invaders.

Two-thirds remain intact and well-preserved, since they were used for defence right up

until the 19th century.

There were 18 grand gates, such as this one, known in ancient times as Porta Appia.

Flanked by two semi-circular towers, it was later renamed Porta San Sebastiano.

The wall incorporated many existing structures like this Egyptian-style pyramid built in

12 BC as a tomb for Caius Cestius.

At the southeastern part of the ancient district are the red-brick ruins of the Baths of Caracalla.

Completed in 217 AD, and covering over 11 hectares, the massive rooms were enjoyed by

Romans for over 300 years.

The complex was able to accommodate up to 1600 citizens, providing not only bathing,

but a library, a gymnasium, galleries, restaurants and even brothels.

Today, it hosts the Rome Opera company during the summer, having staged the first concert

of the three tenors in 1990.

We arrive in the heart of the city at the imposing and impressive Colosseum, the largest

building constructed in the Roman Empire.

Despite its decay, it remains a remarkable feat of architecture and engineering.

The amphitheatre held 50,000 spectators who assembled, for no charge, in tiered seating

arrangements that reflected the hierarchies within Roman society. Below ground were rooms

that contained mechanical devices and cages for wild animals, which could be lifted to

appear centre stage.

Aiming to increase their popularity, the Emperors would stage fights to the death between gladiators

and animals or simply between gladiators themselves.

It was made of concrete and stone yet originally clad in marble, which was later incorporated

into the construction of St. Peter's Basilica and other landmark buildings.

In the present day, visitors are allowed to view the interior of the arena, and, recently

in 2010, the subterranean passageways were opened to the public.

The site is still used ceremoniously by the Catholic Church on Good Friday, as a starting

point for the torchlit procession led by the Pope, known as The Way of the Cross.

Although dwarfed in size by its neighbour, the Arch of Constantine is not short of historical

significance. One of three remaining imperial triumphal arches, the edifice, commemorates

Constantine's victory in a 4th century Civil War.

Ironically, the decorations aren't as well-preserved as those from earlier eras -- and it's almost

a symbol for the eventual fall of the Roman Empire.

We shift from the entertainment hub to the centre of Roman public life at the Forum.

For over 1000 years, this rectangular plaza hosted elections, Senate assemblies and triumphal

processions.

The complex of ancient ruins includes government buildings, temples, arches and basilicas,

giving visitors some idea of the Forum's original layout.

Perhaps no landmark in the Forum remains as intact and well-preserved as the Arch of Septimus

Severus. Erected in 203 AD to commemorate the Emperor's victory in Parthia, the structure

originally had a flight of stairs running through the 12 meter high centre passage.

The arch became property of a church in the Middle Ages, and unlike other monuments such

as the Colosseum, its parts were protected and not incorporated into new buildings.

According to legend, Rome's founding dates back to 753 BC when twin brothers Romulus

and Remus settled on this site, marking the beginnings of the Roman Kingdom.

Today, the Palatine Hill is an open-air museum containing ruins of large imperial buildings,

such as the Palace of Septimus Severus.

During the Republican era, the top of the Palatine Hill became the exclusive residential

area for the rich and powerful, not least for the amazing vistas over the city.

Augustus, Cicero and Marc Antony all resided here.

One of Rome's modern landmarks is the 18th century Spanish Steps, connecting a piazza

to a 16th century French church.

This symmetrical and elegant structure has twelve flights of stairs with total of 138

steps, and is the widest staircase in Europe.

Nearby is the oval-shaped square, Piazza del Popolo. Tourists flock to see the ancient

Egyptian obelisk in the centre, but it was the Porta del Popolo that made an impression

upon those arriving in the Renaissance era. The large gate welcomed pilgrims entering

the city along the Via Flaminia, which connected Rome to the Adriatic coast.

Another example of the opulent palaces built by wealthy families of Popes, is The Villa

Borghese.

Situated on the outskirts of Rome at the time of its construction, it was built by a cardinal

who was the nephew of Pope Paul V, and to this day showcases the Borghese family's collection

of paintings, sculptures and antiquities.

Erected during the late renaissance in a classical style, the Villa became a publicly-owned gallery

in 1902

Heading toward Vatican City, we stop first at Castel Sant' Angelo, a national museum

that once stood as a refuge for Popes facing an imminent threat. Originally a mausoleum,

the castle was fortified and incorporated into the Aurelian Wall, transforming it into

a Papal fortress and luxurious residence.

Occupying less than half a square kilometre and completely encircled by Rome, is Vatican

City.

It's the world's smallest country and spiritual centre for over a billion Catholics worldwide.

St. Peter's Basilica was built on Vatican Hill as a shrine to St. Peter, one of the

twelve apostles and considered the first Pope.

He died as a martyr and was buried on the site in 64 AD.

Construction of the present buildings commenced in the early 1500s. The greatest Italian architects

of the era spent over 100 years building the new basilica, and it was finally re-consecrated

in 1626.

Although millions flock to Vatican City each year, it is home to only 800 residents.

Arguably the best panorama of the Eternal City is from the base of giant lantern that

caps the oculus atop the ribbed vault of St. Peter's Basilica.

A masterful collaboration of between Bramante and Michelangelo, the massive cupola has a

diameter of 42 meters and rests on four huge pillars, which support a cylindrical drum

that features 16 windows.

At a height of 136 metres, this crowning piece is the tallest dome in the world.

Such a magnificent and imposing structure as St. Peter's would be incomplete without

a grandiose esplanade to welcome those taking in its splendour.

The Baroque-style piazza was designed by Bernini in the 17th century.

The elliptical circus that slopes towards the Egyptian obelisk at its centre, is surrounded

by massive colonnades symbolising the Church's outstretched arms greeting its communicants.

Bernini also sculpted the 140 statues of saints that perch on top of the balustrades of each

colonnade. Historian Banister Fletcher referred to the piazza as the "greatest of all atriums

before the greatest of all churches in Christendom."

As we prepare to leave Rome, we capture yet another fantastic approach to viewing the

city in the form of a hot air balloon, tethered about a half kilometre above the beautiful

Borghese gardens. The vista is our last look at the Italian capitol, as we continue east

into the hills toward Tivoli.

We take a slight detour, southeast of Rome, to a sacred grotto in the hills of Subiaco.

Built into the cliff on Mount Taleo, is this brown-hued stone monastery that enshrines

the cave, deemed the Sacro Speco, where St. Benedict lived as a hermit for three years,

before organizing his first monastic community a few kilometres from here.

Most of the monastery's Gothic style buildings were constructed in the 13th and 14th centuries,

hundreds of years after St. Benedict's lifetime.

The monastery is still active, and open for visitors to pray and explore.
