The citadel in Bonifacio, Southern Corsica, France

Built to last. The citadel in Bonifacio, Southern Corsica, France

Set at Corsica's southern tip, Bonifacio watches over the strait to Sardinia, its limestone cliffs rising dramatically above the sea. Once a coastal fortification guarding vital Mediterranean trade routes, the town has evolved into a charming harbour community. Its 9th-century citadel, with quiet passageways and cobbled streets, still echoes with history.

Diu tells a similar story along India's western coast. This fortified town, located at the eastern edge of Diu Island, was once a strategic Portuguese outpost protecting busy sea lanes. Today, Diu is known for its massive fortress, colonial-era cathedral, and quiet charm. Ranked among the country's least populated districts, it remains a fishing hub, carrying forward a legacy of maritime resilience and cultural heritage.
