Athens was named after Athena the goddess of wisdom. Scented with mythology, Athens is a sociable city enlivened by outdoor cafes, pedestrian streets, parks, gardens and urban eccentrics. Almost every house and apartment has a balcony bulging with geraniums, and many of the city's streets and squares are fringed with orange trees. Even though you've probably come here to see the "glory that was Greece," perhaps best symbolized by the Parthenon and the superb statues and vases in the National Archaeological Museum, your best moments may come sitting at a small cafe, sipping a tiny cup of the sweet coffee.

Budapest looks its most beautiful at dawn, yet it is also spectacularly appealing at night. Even more exceptional is the perfect contrast between the right and left banks. Buda is built upon hills, the feet of two of them - Castle Hill and Gellért Hill - almost stand in the water. Facing it is Pest, as flat as a pancake. This is a vibrant city: it throbs with life morning, noon and night; visitors arriving from other countries get the feeling that something interesting is happening round every corner. Budapest is a remarkable and wholly unpretentious place.

Istanbul is one of the truly great romantic cities. Istanbul is home to a layering of civilization on civilization, of empire built on empire. A stroll through this historic city will reveal ancient Roman hippodromes, peristyles, and aqueducts, the greatest excesses of the Byzantine Empire and the mystique and power of the Ottoman Empire. In this sprawling, continent-spanning city you can tramp the streets where crusaders and janissaries once marched; admire mosques that are the most sublime architectural expressions of Islamic piety; peer into the sultan's harem; and hunt for bargains in the Kapali Çarsi.

Paris assaults the senses, demanding to be seen, heard, touched, tasted and smelled. Gaze impressive monuments and savor its gourmet pastiche of cheese, chocolate, wine and seafood. Paris is a city of vast perspectives and intimate streets, of formal espaces verts (green open spaces) and of quiet squares. Paris is relatively small as capitals go, with distances between many of its major sights and museums invariably walkable. Unforgettable walks exhibiting the best of Paris: stroll down the Champs-Elysees for the chic grand boulevard experience and Rue Cler for a more intimate snapshot of Parisian living.

Rows of steeples stacked on onion domes pierce the sky, earning Prague the name "The City of a Hundred Spires". Prague has stood the test of time: 1,000 years of art and architecture have collided with power politics and religious conflicts. New shops and restaurants have opened, expanding the city's culinary reach far beyond tradition. The arts and theater are thriving in the "new" Prague. The arts of the new era possess a distinctive Czech flavor. All of this frenetic activity plays well against a stunning backdrop of towering churches and centuries-old bridges and alleyways.

Rome is Italy's treasure, packed with masterpieces from more than two millennia of artistic achievement. Modern Rome has one foot in the past, one in the present. Find a cafe at summer twilight and watch the shades of pink turn to gold and copper before night finally falls. That's when another Rome comes alive; restaurants and cafes grow more animated and after dinner you can have a gelato (or an espresso in winter) or stroll by the fountains or through Piazza Navona, and the night is yours.

With sumptuous palaces and romantic waterways, Venice is straight out of an 18th-century Canaletto masterpiece. No matter how many times you have seen it in movies or TV commercials, the real thing is more surreal and dreamlike than you ever imagined. Its landmarks, the Basilica di San Marco and the Palazzo Ducale are exotic mélanges of Byzantine, Gothic, and Renaissance styles. It is full of secrets, ineffably romantic, and - at times - given over entirely to pleasure. You must walk everywhere in Venice and where you cannot walk, you go by water.

City of music, cafes, waltzes, parks, pastries, and wine - that's Vienna in a nutshell. Vienna doesn't hurry, and, as you saunter through its stately streets, marveling at its Baroque palaces, neither should you. Explore churches filled with statues of golden saints and pink-cheeked cherubs, wander through treasure-packed museums, or while away an afternoon in one of those countless meccas of mocha (the inevitable cafés), you will feel lapped in lashings of rich, delicious, whipped cream - the beloved Schlagobers that garnishes most Viennese pastries.
