Which Baroque architect designed the Chapel of the Holy Shroud in Turin?

Guarino Guarini designed the Chapel of the Holy Shroud in Turin.

The chapel was built to house the Shroud of Turin and connect Turin Cathedral with the Savoy royal palace. Guarini, a Theatine priest, architect, and mathematician, took over the project after arriving in Turin in the 1660s. His design is famous for its daring geometry, interlocking arches, and a dome that seems to dissolve upward into light.

Construction began before Guarini’s decisive involvement, so references may mention earlier planners such as Amedeo di Castellamonte. That does not change the canonical answer: Guarini supplied the celebrated design and directed its later development. The chapel was completed in 1694 and suffered severe fire damage in 1997 before reopening after restoration in 2018.
