(b. 1624, Modena, d. 1683, Milano)
San Lorenzo, Turin
The church of the Theatine order, San Lorenzo, lies directly adjacent to the cathedral and the royal palace in Turin. The exterior is minimalist in style, only the dome stands out. The ground plan is based on an octagon with its eight sides convex to the central space. Palladian structures frame these segments. The principles on which Guarini's design was based are clear: the dome received most of his attention.
