Sighisoara rises above the Târnava Mare River as one of the few medieval citadels in Europe that is still lived in and admired today. Its historic center has been on the UNESCO World Heritage List since 1999, recognized for its long history as a fortified Saxon settlement and its role in trade and defense on the edges of central Europe. Wander through cobbled alleys framed by pastel-colored houses, and the layers of time feel close at hand, from the city walls and guild towers to busy cafés.

Shanghai is a city where contrasting timelines meet at every corner. Once a small fishing village along the Huangpu River, it grew rapidly during the 19th century into a major trading port.
