The Kong Family Mansion (Kongfu) is the ancestral home of the direct descendants of Confucius — 450 rooms spread across three parallel axes, occupied continuously by the Kong family from the 2nd century BCE until 1948, when the 77th-generation descendant fled to Taiwan with the Nationalist government. The mansion's rooms retain their original furniture, account books, kitchenware, and personal objects exactly as they were left; there is no reconstruction or reproduction, simply the accumulated material of a family that has been there since before the Roman Empire.
The contrast between the formal state apartments (where the Duke of Yansheng received imperial officials) and the domestic quarters (where the family ate, slept, and argued for two millennia) is striking. The ancestral shrine at the rear of the mansion has the most atmospheric interior in the complex. Allow two hours; the mansion is immediately adjacent to the Temple of Confucius and is covered by the same entry ticket (combined Three Kong Sites ticket: ¥150).
