Inside the left transept is the monumental Royal Tribune, built in 1583 by Carlo Emanuele I. In 1777 it was
enlarged from a design by the royal architect Francesco Martinez, Filippo Juvarra’s nephew . Over the years,
the kings of Piedmont and Sardinia, and their families appeared at it, surrounded by the court. The Shroud is
now kept at the bottom preserved in an urn of glass and aluminum.
