Ho Chi Minh City, formerly known as Saigon, is the most populous city in Vietnam at 9 million people. It is an enticing mix of the old and new, with European architecture due to French colonization to towering skyscrapers and modern shopping malls.
Passau sits on the confluence of the Danube, the Inn and the Ilz, so it is fitting that it is known as "the Dreiflüssestadt", which means the “City of Three Rivers.” The historical center offers a cathedral, churches and museums to explore, and the embankment is perfect for a romantic stroll.
Florence (Firenze) is a compact city, but densely packed with spectacular art and architecture everywhere you look. The city center itself is a UNESCO World Heritage Site.
