Athens is the cradle of the Western democratic tradition, home to a civilization as radiant as any before or since. Feel the pulse of history as you climb to the hilltop Acropolis, home to some of the city’s most renowned ancient sites. Gaze in amazement at the massive columns of the Parthenon, Pericles' greatest monument. Admire the little Temple of Nike and the fantastic carvings of the caryatids that support a porch of the Erechtheion. At the bottom of the hill, the Acropolis Museum includes original statues of the maidens and numerous other artifacts unearthed here.

The Venetians left their mark in Nafplio. Perched on a cliff jutting into the sea, their impregnable fortress is an elegant display of Venetian might. Walk through the Old Town with its handsome neoclassical buildings and balconies dripping with bougainvillea. One of the most beautiful towns in Greece, Nafplio is also one of the most historic; its cultural roots date back to both the Argonautic expedition and the Trojan War. From here you can drive across the Peloponnese where tales from Homer’s Iliad come alive.

Simply arriving in Kotor is an unforgettable experience. One of the world’s most breathtaking waterways, the fjord-like Bay of Kotor follows a winding path through the forested mountains that rise on all sides of the sparkling sea. Nestled along the most inland cove are the coral-tiled roofs of Kotor, a UNESCO World Heritage site. Fortified during Venetian rule, medieval ramparts surround the Old Town, where visitors will find historic landmarks such as the 12th-century Cathedral of St. Tryphon and the Maritime Museum. The physically fit should climb the 1,350 steps to clifftop St.

Coastal Slovenia’s largest town, Koper is something of a well-kept secret. Koper’s central core is delightfully medieval and rich in history. Not far from the port, the Old Town centers around Titov Trg, a plaza filled with Venetian-influenced landmarks, from its Gothic-style loggia to the Praetorian Palace and Da Ponte Fountain, a replica of Venice’s famous Rialto Bridge. The Cathedral of The Assumption, also called Koper Cathedral, features a four-story tower with sweeping bay views and houses one of the oldest bells in Slovenia.

Bronze bodies bask in the sun on golden beaches, blue-domed churches dot the island, and picturesque windmills paddle the horizon. This is Mykonos, one of the most charming and fashionable of the Greek isles. Chora, its capital, is a cubist jumble of whitewashed houses and a maze of alleyways built long ago to foil pirates. Get lost in these narrow, twisting lanes filled with exclusive boutiques, art galleries and world-class restaurants.

Super yachts crowd the harbor and waterside bars hum with wealthy vacationers and young partiers in this posh island getaway with a laid-back Mediterranean vibe. The island of Hvar is famous for its lavender fields, vineyards, year-round sunshine and nonstop nightlife, but it’s also rich in culture and history. Near the harbor stands a Benedictine convent where nuns fashion lace as part of a 150-year-old tradition recognized by UNESCO as an Intangible Cultural Heritage.

It was English poet Lord Byron who famously described the great walled city of Dubrovnik as “the pearl of the Adriatic” and George Bernard Shaw stated that “Those that seek paradise on earth should seek it in Dubrovnik.” Red tiled roofs and a backdrop of green hills contrast sharply with the spectacular blue of the Adriatic. Thick medieval walls wrap around beautiful Gothic, Renaissance and Baroque churches, monasteries, palaces and fountains. This UNESCO World Heritage site played a central role in the TV show Game of Thrones.

History oozes from every corner of Corfu, an island prize coveted by a succession of maritime powers since the Peloponnesian War in the 4th century BC. But who can blame them? This Ionian idyll is the greenest of all Greek islands, swathed in orange and olive groves and endless beaches bathed by a cerulean sea. A UNESCO World Heritage site, the Old Town of Corfu includes the magnificent Esplanade, where you can watch a game of cricket from a sidewalk café. There are also beautiful palaces, castles and archaeological sites to explore.

Make sure to be on deck to witness sailing into one of the Aegean’s most spectacular sights: the volcanic caldera that is Santorini’s bay. Rising from the sea, the earth transforms into a wall of stone that looms in striating hues of ochres, grays and pinks. Dotted with the island’s iconic blue-domed churches, the whitewashed village of Fira hovers in the cliffs, bustling with shops, tavernas and a fine museum while clinging to the caldera’s rim.
