chiesa di San Giuseppe dei Teatini (戴蒂尼会圣若瑟堂)

The church was built at the beginning of the 17th century by Giacomo Besio, a Genoese member of the Theatine order. It has a majestic though simple façade. In the centre niche is housed a statue of San Gaetano, founder of the order. Another striking feature is the large dome with a blue and yellow majolica covering. The tambour decorated with double columns, and was designed by Giuseppe Mariani. The belfry tower was designed by Paolo Amato.
The interior has a Latin cross plan with a nave and two aisles, divided by marble columns of variable height. The inner decoration is a nearly overwhelming parade of Baroque art, with stuccoes by Paolo Corso and Giuseppe Serpotta. Frescoes decorate the nave ceiling and the transept vault, painted by Filippo Tancredi, Guglielmo Borremans and Giuseppe Velasquez. The frescoes were severely damaged during World War II, but have been accurately restored. The most important piece of art is however a wood crucifix by Fra' Umile of Petralia.
The crypt houses remains of a former church, dedicated to Madonna of Providence.
