	"Kulou" means arsenal and storied building, is a constellation in the area of modern [[Centaurus\|Cen]]/[[Lupus\|Lup]] created by ancient Chinese astrologers, dating back to the 2nd century BCE. It is classified as one of the "external" constellations (外官) of the Shi School (石氏), as it belongs to the Shi School's constellation system during the Han Dynasty, and it is outside of the 28 lunar mansions.

	In Sima Qian's "''Book of Heavenly Officials''" (天官书), an early reference to Kulou is made, though the exact number of stars is not specified. The text provides a vague description: "南众星曰天库楼，库有五车" ("The southern group of stars is called Tian Kulou, with five chariots in the arsenal"), but it mentions "five chariots" instead of "five pillars," and makes no mention of Heng. Similarly, the "''Huangdi Zhan''" (黄帝占) follows the same naming convention, referring to Kulou as the "Outer Ku" (外库) and describing the five pillars as "Wu Che" (five chariots). This suggests that the early Ku Lou constellation's five pillars/chariots were likely all contained within the arsenal.
