Sweden is a country where medieval towns, coastal archipelagos, and expansive forests sit side by side with modern design and a strong cultural identity. Stockholm, the capital, is built across 14 islands connected by bridges and ferries. The historic district of Gamla Stan features narrow, cobbled streets and colorful buildings dating back to the 13th century.

This city, which started as a modest fishing village, now offers plenty of modern German charm. The extensive public transportation makes it a perfect home base for seeing nearby attractions such as Heidelberg. Mannheim is known for its many pretzel stands, so make sure you indulge in one of these delicious treats before you leave!

Asmara, the capital of Eritrea, is a city where time seems to have paused in the mid-20th century. Known for its remarkably preserved Italian modernist architecture, the city has earned recognition as a UNESCO World Heritage Site.

Ronda, perched high above the El Tajo gorge in southern Spain’s Málaga province, offers one of the most dramatic landscapes in Andalusia. The city is split in two by a 120-meter-deep canyon carved by the Guadalevín River, and connected by the iconic Puente Nuevo, an 18th-century stone bridge that took over 40 years to complete. Visitors crossing the bridge can stop at the viewpoint built into the stone itself, once used as a prison.

Spectacularly picturesque, Montreux is situated on the shore of Lake Geneva and one of Switzerland's most popular resort destinations. Montreux is best known for stunning lakeside views, upscale hotels, an annual jazz festival, and the magnificent Château de Chillon, the medieval castle which inspired the writings of many Romantic era poets.
