One of the Three Enclosures in ancient Chinese astronomy, the Central Enclosure lies at the heart of the northern sky. Also known as the Purple Forbidden Enclosure, it revolves around the North Star, flanked by two satellite asterisms to the east and west, comprising fifteen stars in total. These two arcs form a celestial wall that encircles the center like clasped bows.
