Shanghai spans centuries in a single skyline, and this shortlist captures the contrast best. The Oriental Pearl Tower and the riverside Bund face off across the Huangpu, pairing futuristic architecture with colonial-era facades, while a Shanghai River Cruise lets you take in both without rushing between them. Inland, the Yu Garden and adjoining Old City preserve classical courtyards and teahouses, and the Jade Buddha Temple adds a quieter, spiritual counterpoint. Round it out with the Shanghai Museum for context on everything you have seen, and Nanjing Road Pedestrian Street for the city's modern retail energy. Together they deliver old and new Shanghai in one efficient loop.
