The Guggenheim Museum Bilbao is a landmark of contemporary architecture and a cultural beacon for the city. Designed by Canadian-American architect Frank Gehry, the museum's fluid, sculptural form has been hailed as one of the most significant architectural achievements of the 20th century. Its titanium-clad curves and organic shapes have transformed the Bilbao skyline and are often likened to a ship or flower. Beyond its jaw-dropping exterior, the museum houses a world-class collection of modern and contemporary art, focusing on postwar American and European artists. Notable works include pieces by Mark Rothko, Jeff Koons, and Louise Bourgeois, among others.

In Bruges’ Golden Age — the 15th century — art was a big deal. Leading artists of the day, like Jan van Eyck and Hans Memling, came to live and work in the city. Today, you can marvel at the masterpieces of the world-famous Flemish primitives in the Groeninge Museum and the St. John’s Hospital. And in the treasury of Bruges’ oldest parish church, Saint Saviour’s Cathedral, you can also come face to face with other priceless paintings that were created in the city in centuries gone by.

Inaugurated in 1811, Gamla Stenbron, in Swedish Östra Bron, is the longest stone arch bridge in Sweden which, with its 168 meters, is considered a city landmark in Karlstad.
