Oratorio di Santa Caterina in Fontebranda
The Oratory of Santa Caterina in Fontebranda, also known as the Oratory of the Tintoria, is a small church built between 1465 and 1474 by Francesco di Duccio del Guasta. After the canonization of Catherine of Siena by Pope Pius II in 1461, the inhabitants of the Sienese district of Fontebranda wanted to build a church dedicated to the saint who was born and lived there. It was therefore decided to demolish the old dye works of Jacopo Benincasa, the saint's father, and two adjacent houses to create a space for the church.
