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.

Córdoba, located in the heart of Andalusia, was once the most advanced city in Western Europe. During the 10th century, it served as the capital of Al-Andalus and was a center for learning, science, and art. Today, visitors walk the same streets that philosophers, poets, and physicians once crossed. The city’s most famous landmark, the Mezquita-Catedral, reflects its layered past. The red and white horseshoe arches inside are one of the most photographed interiors in Spain.
