The Palace Museum, also known as the Forbidden City, is far more than a museum collection inside a famous historic shell. The buildings, courtyards, gates, and ceremonial layout are the reason most visitors come, and the experience depends as much on moving through that setting as it does on what is displayed inside.
For first-time travelers, this is often the clearest place to understand Beijing's imperial scale. It also takes more time and energy than many expect. The strongest Palace Museum day is usually a focused one: give the site enough attention, then add only one nearby follow-on if you still have time and energy left.
