The Basilica of St Felix is one of Girona’s oldest churches, a site of continuous worship since the early Christian period. Its architecture is a palimpsest of styles: a Romanesque core, a majestic Gothic nave, and a Baroque façade topped by a distinctive truncated bell tower. The interior safeguards priceless treasures, including eight rare Roman and early Christian sarcophagi and the ornate 14th-century Gothic tomb of Sant Narcís, the city's patron saint. Though never the cathedral, its historical and artistic importance is profound. It remains an active parish church, offering a quieter but deeply atmospheric counterpoint to the larger cathedral nearby.

From the other side of the mouth of Bouregreg River, Salé, the old city of pirates and Rabat's rival sister, faces the capital. Founded before Rabat at the start of the 12th century, its medina, lined with fountains, magnificent riads, and mosques, buzzes with activity. Don’t forget the medersa, the Koranic school, a renowned chef-d’oeuvre of Merinides art.

The Cheonggyecheon was originally a creek that flowed through downtown Seoul -- in the wake of rapid post-war economic development, it was buried under concrete to facilitate urban expansion. Today, however, the over 10 km-long creek and its banks have been uncovered and remodelled into an exciting recreational area for locals and tourists, with clean water and natural habitats bordering on residential and office buildings.
