Santissima Trinità delle Monache is a large former monastery and church in central Naples, Italy; it now serves as a military hospital.
The monastery and church was founded in the early 17th century by the noblewoman Vittoria de Silvia.
She had refused at the last minute to marry the Count di Biccari, Emilio Caracciolo, and instead retired to a convent, initially choosing the convent of San Girolamo a Mezzocannone, Naples.
But wishing to move, she established this convent near the church of Santa Maria Ognibene ai Sette Dolori and the convents attached to Santa Maria della Sapienza and San Giovanni Battista delle Monache.
In 1625 Cosimo Fanzago added the stairs at the entrance of the church, and sculpted some of the marble telamons.
