Geography sets La Coruna apart from other Galacian cities, with its historic centre built on a headland and surrounded by beaches and a busy port. Above the city, the Romanesque Tower of Hercules stands in stark contrast to the modern vibe of this seaside Spanish metropolis.

Oviedo is a treasure trove of Spanish religious architecture, dotted with monasteries, cathedrals and shrines that date all the way back to the 9th century. Soak up the rich history of the city by experiencing El Fontán Market, the San Isidoro el Real Church and the Castle of San Juan de Priorio, then shift aesthetic gears and check out modern architectural gems like the Prince Felipe Auditorium and the Jirafa building.

travellers generally come to Bilbao to see the Guggenheim—some for the art inside, but many for the amazing building itself. The Fine Arts Museum and the Basque Museum may not have been designed by Frank Gehry, but are worth a visit, and you can catch international opera stars at the Palacio Euskalduna.

Plan to cross many bridges when in Cork. Ireland's third-largest city began life as an island and now spans both banks of the River Lee, with watery channels running beneath some of its main thoroughfares. The best way to experience this hilly southern seaport is on foot, following the signposted walking tour past St. Finn Barre's Cathedral and the riverside quadrangle of University College up the hill to red and white Shandon Church. Along the way, you'll meet plenty of the city's talkative residents.
