Visit prehistoric Stonehenge, built in 3,000 BC, a mysterious monument of four concentric rings of hefty stones, believed to be a sacred place of worship or some type of calendar. Like a Jane Austen novel come to life. Bath was England's most fashionable spa town in the 18th century. Everyone who was anyone headed to this town on the River Avon to "take the waters" and attend the theaters. Today you'll visit Roman baths, sweeping Georgian-style terraces and buildings made from the honey-hued stone, and art galleries, shops and restaurants.

Join a licensed local guide for an in-depth look at London, from the royal haunt of Buckingham Palace (the official London residence of King Charles III) to the slightly more democratic Speakers’ Corner of Hyde Park, where anyone can pull up a soapbox and orate to his heart’s content. You’ll see the changing of the guard (season permitting), the clock tower of Big Ben with its 14-ton bell, and Westminster Abbey, where almost every English king and queen since William the Conqueror has been crowned. After a stop at the Houses of Parliament, continue on to the magnificent St. Paul’s Cathedral, the masterpiece of London architect Christopher Wren.

See Trafalgar Square, often used for community gatherings and political demonstrations.

Get up close and personal with the Tower of London. Towers, rather. Twenty stone towers, as well as tunnels, winding staircases and narrow passageways comprise this huge fortress covering 18 acres on the banks of the Thames. A royal residence from the 11th - 16th centuries, the Tower also served as a jewel safe and a prison. The headless skeletons of Anne Boleyn and Catherine Howard (Henry VIII's former wives who were executed here) are believed to be buried here. The Crown Jewels are housed here, including the largest cut diamond in the world (530-carats). Beefeaters (guards) lead tours through the Tower.

Take the Eurostar under the English Channel. Faster than you can say... anything, in French, you'll whiz through a tunnel and arrive in Paris.

What's that huge white arch at the end of the Champs-Élysées? The Arc de Triomphe, commissioned by Napoleon in 1806 after his victory at Austerlitz. Your licensed local guide will elaborate on this, and other Parisian landmarks. See some of the most famous sites, including the ornate 19th-century Opera, the Presidential residence and the Place de la Concorde, where in the center you’ll find the Obelisk of Luxor, a gift from Egypt in 1836. Spot chic locals (and tons of tourists) strolling the Champs-Élysées. Look up at the iron girders of the Eiffel Tower, built for the 1889 World's Fair to commemorate the centenary of the French Revolution.

See the city from the water on an hour-long cruise along the River Seine. The Seine cuts right through Paris, dividing the city in half. See the Eiffel tower rising up on the Left Bank, the walls of the Louvre on the Right Bank. A guide will point out other monuments and architectural marvels as you pass, many of which are illuminated by clear white light at night.

The world's largest art museum, the Louvre is housed in a Medieval fortress-turned-castle so grand it's worth a tour itself. You walk through the 71-foot glass pyramid designed by I.M. Pei and added in 1989, and step into another world--one with carved ceilings, deep-set windows, and so many architectural details you could spend a week just admiring the rooms. The Mona Lisa is here, as well as the Venus de Milo and Winged Victory (the headless statue, circa 200 BC, discovered at Samothrace). The Louvre has seven different departments of paintings, prints, drawings, sculptures and antiquities. Don't miss the Egyptian collection, complete with creepy sarcophagi, or the collection of Greek ceramics, one of the largest in the world. (Please note the Louvre is closed on Tuesdays.)

A lively role-play puts you in the shoes of the monarchy, clergy, nobility, bourgeoisie, or peasantry to explore the issues underlying the French Revolution.

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.

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! Despite its unfinished state, the church has 18 spindle-shaped towers that soar above the church itself, making for a striking addition to Barcelona’s skyline and more than worth the visit.

The enormous Baroque palace currently has more rooms (2,800) than any other European palace, but it was originally supposed to be four times as large.
