Unjustly overlooked by travellers en route to Tunisia's celebrated seaside resorts, the nation's capital certainly deserves more than just a quick glance through the shuttle bus window. The city lives and breathes history, from the crumbling columns of Carthage to Medina's labyrinthine alleys, where the scent of orange blossom mingles with freshly baked tabouna bread. This is where Roman mosaics, Ottoman arches and mid-century modernism collide with unshowy authenticity.

Zaragoza, the capital of Spain's Aragon region, has a privileged location, equally distanced from Madrid, Barcelona, Valencia and Bilbao. The city is connected by an international airport and a high-speed railway line (AVE). Visitors can expect a delicious gastronomy and a rich heritage of historical monuments: Basilica del Pilar, Cathedral of San Salvador, Aljafería Palace, the paintings of Goya or the Mudejar–UNESCO Heritage of Mankind. Local architecture combines Islamic and Gothic styles — an absolute must-see.

Straddling the Adriatic Sea where it plunges deepest into Europe, Rijeka boasts a rich maritime history. Croatia's third largest city and the heart of Primorsko-Goranska County, its charm lies in its hospitable spirit and diverse cultural heritage. As you amble along the Habsburg-era Korzo promenade, peek into the 19th-century National Theatre, graced with Klimt's artwork. Soak up the sweeping views of Kvarner Bay's islands from Trsat Castle. A cosmopolitan harbour of coexistence, welcome to Rijeka.

Nestled in the corner of rural south-west France stands Pau, the capital of the Béarn province, a bastion of history and culture. The town occupies a unique geographical position in the foothills of the Pyrenées. With its awe-inspiring views of the mountain range, Pau is only a few hundred kilometres from the major towns of Bordeaux and Toulouse and even closer to Spain and the Atlantic Ocean. A springboard to sunny beaches or snow-capped mountains, Pau’s pretty streets, and excellent gastronomy are enough to ensure leaving will be difficult.
