The jewel of Granada is the Alhambra, a stunning palace and fortress complex that dates back to the 13th century. This UNESCO World Heritage Site is a testament to the city's Moorish past, showcasing intricate Islamic art and architecture.

Liège, located along the Meuse River in eastern Belgium, is a city shaped by industry, resilience, and an independent spirit that dates back centuries.

Every Sunday, locals gather at La Batte, one of the oldest and largest outdoor markets in Belgium.

Bordeaux is ready for its close-up! After years of improvements, modern public transportation is in place and the city is gleaming after a wave of restorations.

Philadelphia, the birthplace of American democracy, offers visitors a rare opportunity to walk through the very streets where the nation’s founding ideals were debated, signed, and set into motion.

The Philadelphia Museum of Art is home to works by Van Gogh, Duchamp, and an entire Japanese teahouse, but it might be better known for the "Rocky Steps" out front, where visitors recreate the famous movie scene daily.

Bartolomé Island, one of the most iconic destinations in the Galápagos archipelago, is known for its dramatic volcanic landscape and the postcard-perfect view from its summit.
