The Xiajiadian Relics Cluster

The Xiajiadian Relics Cluster

The Xiajiadian Relics Cluster is a National Key Cultural Relics Protection Unit.

The site covers an area of 38,000 square meters, including 150 house foundations and 150 storage pits. Judging from the overall layout of the courtyards, each one has a main room, auxiliary rooms, and storage pits, reflecting the family structure of the time. Shared boundary walls and alleys between courtyards indicate relationships among different families. At the center of the settlement, there is a courtyard situated on higher ground, featuring grand architectural specifications and a small square in front of the house—indicating that the household was of higher status. This suggests there were already clear social hierarchies at the time. All this evidence proves that the Xiajiadian Lower Culture period had achieved a relatively advanced level of social development.

The Xiajiadian Lower Culture site is commonly referred to as a "large ash mound," which has a specific historical meaning. When ancient humans selected dwelling sites, they had certain requirements: a sunny location, access to water sources nearby, and the ability to manage a certain farming area. After building their houses, the ashes produced from daily use of fire were discarded into pits beside the houses or simply piled around them. Over time, as the houses gradually deteriorated and collapsed, the surrounding piles of ash grew larger. The ancients would then backfill the old houses with these ashes and build new ones on top of the old foundations. After many years of this process, the houses became increasingly elevated, eventually forming what is known as a "large ash mound."
