The Dharani Sutra Pillar of Zhao County, also called the Stone Pillar, was built in the Northern Song and is about 16 metres tall, the largest sutra pillar that survives. Its shaft consists of several octagonal tiers of stone inscribed with dharani texts and carved with lotus petals, Buddha figures and guardian warriors in elaborate form. Liang Sicheng calls it the largest sutra pillar of the Song.
