Stockholm is the most populated urban area in the Nordic countries – ironic, since it’s a bunch of islands, rather than a solid land mass! The capital of Sweden accounts for more than one-third of the country’s GDP, and is perhaps most famous for the ‘Stockholm Syndrome’ incident, but it’s also home to the Nobel Prize. Its metro system is the longest ‘art gallery’ in the world, boasting incredible graffiti, sculptures, and architecture. The Vasa, a preserved 17th-century ship, is another must-see in the city.

Students attending the Stockholm field trip might write up reflections about the city’s status as Europe’s first ‘green capital’ for a Sustainability stamp in their London Passport – or perhaps capture their explorations of the Photography Museum for an Art stamp.
