The narrow church or oratory of San Gaetano di Thiene is located in the middle of via dei Pispini. The oratory of the aristocratic Contrada del Nicchio (Sea-shell) was built from 1683-1700 . The simple façade sports a large stucco seashell over the doorway. It houses a 14th-century painting depicting a Madonna and Child with Saints , which is likely the icon of Madonna del Forcone that had been previously venerated at an aedicule where the church stands. The interior is frescoed with paintings by Giuseppe Nicola and Apollonio Nasini.
