On the feast day of the Theatine founder San Gaetano Thiene (1480-1547), this image gallery celebrates a few of the order’s churches associated with the saint. Known in English as Saint Cajetan, the younger son of a noble Vicentine family was canonized in 1671. Many of these churches were originally dedicated to other saints, with the dedication to Gaetano added – formally or informally – after his canonization. Others, such as the two unexecuted designs by Guarini, followed immediately in the wake of canonization.
Most of these churches are no longer served by the Theatines, and some (notably Nice) are today known under different dedications. For more (if not all) churches dedicated to the saint, see this Wikimedia Commons category page. All images are in the public domain.
