The Shroud of Turin was made of linen. It is a plain-weave cloth made of flax fibers. The linen is approximately 4.4 meters wide by 1.1 metres long (14.3 feet by 3 feet). The cloth has a herringbone weave, which is an important characteristic of its construction.
The material has undergone various scientific analyses in order to better understand its origin and properties. The exact chemical and historical details of the Shroud’s current form, despite extensive testing, remain the subject of ongoing research.
