Take a walk past Rome's most beautiful and unusual Baroque fountains. At the foot of the Spanish Steps, elegant cafes surround the central fountain. The water pressure here was so low that the artist had to sink the fountain into the ground to get any water going through it, so he went ahead and designed the fountain to look like a sinking ship. There's no shortage of water pressure at the nearby Trevi Fountain, a Baroque extravagance designed by master sculptor Bernini.

View the Trevi Fountain, where it is traditional to toss a coin into the fountain to ensure a safe return to the Eternal City.

We will spend some time in the Piazza Navona area. Built on the foundations of Domitian's Circus, this magnificent square was designed by Borromini in 17th century. It is full of life and is highlighted by one of Rome's most spectacular fountains, the Four Rivers designed by Bernini. The square is often filled with local artists. The surrounding neighborhood is also one of the best places in Rome to get a tasty tartufo or gelato ice cream

Visit St. Peter’s Basilica where from the outside, the church has four rows of columns that radiate out like welcoming arms; inside, the church seems enormous enough to embrace the entire world. The dome, partially designed by Michelangelo, rises 452 feet above the ground. Michelangelo’s mark is everywhere here, from the costumes worn by the Swiss Guards to his exquisite “Pietà” sculpture (the only sculpture he ever signed) to the amazing frescoes of the Sistine Chapel. Because he considered himself a sculptor and not a painter, Michelangelo hated working on these paintings, now considered masterpieces.

The ultimate symbol of Ancient Rome, the Colosseum still dominates the modern city. Tour the amphitheatre with your local licensed guide. Built by the emperor Vespasian in A.D. 72, the structure held almost 50,000 spectators but was so well organized that the entire place could be emptied within 15 minutes. Inside, the spectacles varied from gladiator battles to immense naval contests to wild beast shows, in which thousands of exotic animals like giraffes and ostriches were popped into the stadium through trap doors and left to fight Roman hunters. See the system beneath the floor that operated the trap doors and housed the animals, then continue on to the relative calm of the Forum. Ancient Rome’s commercial, religious and political center, the Forum held markets, temples and the Senate House. Near the Rostra, or speaker’s platform, you can still see game boards scratched into the marble by bored politicians--anyone up for a game of tic tac toe?

Tour the ruins and excavations of the Roman Forum, which features the remains of magnificent temples, basilicas, and triumphal arches that once formed the heart of the Empire.

Immerse yourself in the charms of old-world Firenze. The birthplace and focal point of the Italian Renaissance, Florence still has the masterpieces to prove it. Brunelleschi’s monumental cuploa (dome) atop the city's renowned Duomo dominates the skyline. Your local licensed guide will take you to Giotto's Bell Tower and the aptly named Gates of Paradise, the bronze east doors of the Baptistery that spurred the burgeoning Renaissance. Don’t overlook the tombs of Michelangelo, Galileo, and Machiavelli at the Chiesa di Santa Croce, or Florence’s amazing leather goods. You can check them out when you visit one of the area’s famed workshops!

Spend time in the Piazza della Signoria, the political stage of Renaissance Florence and an open-air museum of sculpture.

Stroll along the Ponte Vecchio, the oldest of Florence's six bridges and one of the best-loved sites of Florence. Lined with numerous shops, visitors often do not realize they are on a bridge until the reach the center arches that look out over the Arno.

Stroll through the narrow and winding streets of Siena to the Piazza del Campo, a vast and lively square in the heart of the city.

Stop in Pisa to see the famous leaning bell tower. It was already partly finished when builders realized that -- surprise! -- the ground beneath was too soft to support it. They tried to correct the tilt by putting a slight bend in the structure, but the extra weight just made it tilt more. Famous as it is, the leaning tower is just one component of Pisa’s Campo dei Miracoli (Field of Miracles). Rising from an immaculate green lawn, the baptistery, duomo, and tower are fine examples of Pisan Romanesque architecture. All three are clad in intricately carved black and white marble, and on bright summer days their brilliance can be blinding.

All three are clad in intricately carved black and white marble. On bright summer days, their brilliance can be blinding.

The Côte d'Azur's largest city spills down the hillsides to pebble beaches that line the shore. Your Tour Director will show you around the narrow pedestrian streets and tiny squares of "Le Vieux Nice" (Old Town), which is sprinkled with old palaces and mansions. Stroll down the Promenade des Anglais, which runs parallel to the water. Backed by Nice's grand hotels, the Promenade was built in the 19th century for the British who flocked here en masse.

Stroll The Promenade des Anglais, named for the English who paid for it, is a seven kilometer walkway along the seafront. Called "La Prom" by locals, it's the best place to people-watch.

A true masterpiece of ancient architecture, the Pont du Gard aqueduct is one of the most beautiful Roman constructions in the region. Discover more about this startling monument as you follow the course of its history through the ages.

Lush lavender fields, olive groves, terra-cotta roofs, and ochre walls lit by golden sunlight...your Tour Director will guide you through the splendor that is Provence. Explore legacies of the Roman Empire like the Pont du Gard aqueduct, a sophisticated work of engineering that is intact after more than 2,000 years, and visit the Nîmes amphitheater. Built by the Romans nearly 2,000 years ago, it was once the site of gory gladiator and animal combat, and is still used today for performances and bullfights (some things never change).

Paella is a Valencian rice dish with ancient roots that originated in its modern form in the mid-19th century near Albufera lagoon on the east coast of Spain.

See brilliant Barcelona, a city of graceful Gothic churches, wrought-iron balconies and grand avenues filled with outdoor cafés. Throughout the city, daringly innovative buildings sit side-by-side with the medieval past. A licensed, local guide will show you some of the high points of this architectural showcase. First stop, the pointy spires of the La Sagrada Familia (Church of the Holy Family), a half-finished church complex that became the obsession of Barcelona's famously eccentric architectural genius, Antoni Gaudí. At the top of Güell Park, another of Gaudí's masterpieces, is a terraced area where you get a fantastic view of the park and Barcelona City. The vibrant colours of the tiles are breathtaking. Then step back to the past with a journey up to Montjuïc (Hill of the Jews), a fortress built atop an ancient Jewish cemetery. This was the site of numerous battles to control Barcelona, and also the location of the 1992 Olympics.

This breathtaking church, said to be the master-work of architect Antoni Gaudí, has been under construction since 1882 and is not expected to be completed until 2026!

Travel to Barcelona’s mountain of Montjuïc, the focal point of two of the city’s key international events: the World’s Fair of 1929, of which many structures still remain; and the 1992 Olympic Games. Montjuïc features the largest "green zone" in the city with miles of forests and parks.

Spend time in Parc Güell, part of the UN ESCO World Heritage Site, 'Works of Antoni Gaudi'. Designed primarily by Gaudí, particularly interesting areas of the park include a mosaic pagoda, a lizard fountain spitting water, an undulating bench decorated with ceramic fragments, and an array of unique Doric columns, which are hollow and serve as part of Gaudí's drainage system.

Take interactive learning to another level with a Tour Director-led treasure hunt of Las Ramblas, the most famous pedestrian street of Barcelona! Complete exciting activities and solve fun clues. Each clue and every activity is built to maximize on-tour experiential learning.

Tapas purportedly originated when bartenders set a small plate ("tapa") over patrons' glasses of sherry and wine to keep the flies out. The bartenders starting piling the plate with cold cuts, olives, or salad, and the bite-size snack was born. (We're unsure how they kept the flies out of the cold-cuts... maybe that's how the sandwich was invented?) Over time these working-class snacks have become more elaborate, with each region adding its own specialties and cooking techniques to create unique tastes and combinations.
