大殿, or "Great Hall," is a significant architectural structure commonly found in traditional Chinese palaces and temples. It serves as a central space for important ceremonies, gatherings, and official functions. The design typically features a grand roof, intricate decorations, and spacious interiors, reflecting the cultural and historical importance of the building. In the context of the Forbidden City in Beijing, the 大殿 is known as the Hall of Supreme Harmony. This hall was used for major events such as imperial weddings and coronations. Its impressive scale and ornate details symbolize the power and authority of the Chinese emperors.
