Pompeii, Italy, is a mesmerizing time capsule that invites travelers to step back into the world of ancient Rome. Once a thriving city, Pompeii was abruptly buried under volcanic ash and pumice following the catastrophic eruption of Mount Vesuvius in 79 AD. This tragic event preserved the city in remarkable detail, allowing visitors today to walk the cobbled streets and witness a snapshot of Roman life, from grand villas and bathhouses to bakeries and amphitheaters.

Vienna has a long memory. Once the capital of the Habsburg Empire, the city still carries signs of its imperial past in its palaces, concert halls, and wide boulevards. Visitors can walk through the Hofburg complex, where emperors once ruled, or tour the opulent rooms of Schönbrunn Palace, which features 1,441 rooms and a maze in its gardens. But Vienna’s many historic buildings now house contemporary art museums, cafés, and institutions that reflect the city’s modern identity.

Boulder, a beautiful 2,500 foot high oasis of green lawns and clean trees-shaded streets where the sun shines over 320 days a year, overlooks the Lake Mead National Recreation Area.

Antigua is a city shaped by centuries of artistry, tradition, and natural forces. Set in a highland valley and surrounded by volcanoes, its streets are lined with colorful buildings, hidden courtyards, and open-air plazas. The Santa Catalina Arch is one of Antigua’s most recognizable features, originally built as a passage between two sections of a convent. Today, it frames a dramatic view of Volcán de Agua and is a popular gathering spot for both locals and visitors.

The River Nile, most often associated with Egypt and its ancient civilizations, actually flows through eight other countries including Uganda, Ethiopia, Sudan, and Kenya.
