Back in 2013, Nantes became the first French city to earn the title of European Green Capital—a recognition of its long-standing efforts in sustainable urban planning. And it didn’t stop there. From car-free zones and electric trams to public parks, bike paths, and nature reserves along the Loire, the city continues to invest in green living. It’s a place where environmental goals actually shape how the city feels and works today.

Valletta, the capital of Malta, was ingeniously constructed in the 16th century by the Knights of St John. Exuding baroque elegance, it is rightfully hailed as an open-air museum due to the number of historic buildings concentrated in the area like St John’s Co-Cathedral and the Grand Harbour, masterfully crafted by the Knights. Within a mere 900m x 630m area, over 25 churches grace the landscape. This remarkable city is an esteemed UNESCO World Heritage Site, a testament to its cultural significance and architectural splendour.

Situated to the west of Östersund, the largest island in Lake Storsjön, Frösön holds a rich historical significance. Named after the Norse god Freyr, the island, which served as the regional centre of Jämtland throughout much of recorded history, boasts the northernmost raised runestone in the world, known as the "Frösö Runestone”. Easily accessible by foot, car, or bus, the island is a short walk across the pedestrian bridge from Östersund. The renowned Swedish composer Wilhelm Peterson-Berger's enchantment with the island led to the creation of "Sommarhagen", now a museum and one of Östersund's most visited attractions.
