Antoni Gaudí's ambitious project remains, as of today, unfinished, which by no means takes away its massive popularity, receiving over 4.5 million visitors every year. The Basílica de la Sagrada Família, or simply La Sagrada Família, is a large unfinished Roman Catholic minor basilica, considered the best example of Modernist architecture. Meticulously crafted to embody the Christian faith through composition, sculpture, and individualistic, offbeat design, this masterpiece is the kind of attraction that has to be experienced to be believed.

A UNESCO World Heritage Site, the island of Delos is an important sacred site for the ancient Greeks, and therefore, a must-visit for history and archaeology enthusiasts. It holds some curios remains of ancient civilisations: a former amphitheatre, historic houses with mosaics, temples, and the famous Terrace of the Lions. Don't skip the museum–it contains some artefacts dating as far back as the 25th century BC.

The enchanting Kiso Valley, nestled in the heart of Japan, is a timeless treasure, where history breathes through its ancient pathways and rustic architecture. Four centuries ago, the picturesque villages of Magome and Tsumago served as crucial staging posts along the 500 km Nakasendo Highway, where feudal warlords journeyed annually to Edo (now Tokyo). Today, these villages retain their historic charm, with Magome seamlessly blending modern amenities with its traditional core, easily accessible by rail and bus from Nagoya. As you step onto the broad foot trail of 'old' Magome, the echoes of the past resonate, transporting you to an era untouched by time.
