Linzi was the capital of the ancient state of Qi for over 600 years during the Zhou Dynasty period, and the earthen walls of the old city — up to 10 meters high in places — still define the area now known as the Linzi district of Zibo. The ruins are substantial enough to walk: the outer walls enclosed an area of roughly 20 square kilometers, making Linzi one of the largest cities in the ancient world at its peak.
The Qi Heritage Museum at the center of the site houses the main archaeological collection: bronze ritual vessels, jade objects, pottery, weapons, and the famous "sacrificial horse pits" where over 600 horses were buried with a nobleman of the Qi ruling house around the 5th century BCE. The chariot museum next door contains original wooden chariots preserved in the soil, a remarkable survival. The site is in the eastern part of Zibo, about 30 minutes from the city center by bus or taxi.
