National Museum of China

Occupying the eastern half of Tiananmen Square, this colossal museum traces China's journey from ancient dynasties through modern times with carefully curated galleries that flow logically from bronze vessels to contemporary art. The scale is immense—plan to be selective rather than exhaustive—but highlights like the Zhou Dynasty bronzes and the terracotta warrior replicas capture millennia of artistic achievement. Free admission makes this one of the world's most accessible windows into Chinese civilization, though crowds can be substantial during peak hours.
