Founded in a noble house in 1607 by Beatriz Ramírez de Mendoza, Countess of Castelar, for the Corpus Christi Jerónimas nuns, the convent owes its name, “carboneras”, to an image of the Virgin Mary found in a coal yard and which was donated to the convent.  In 1981, it was declared a Site of Cultural Interest. 

The maestro, Miguel de Soria, was commissioned with designing and building the ensemble in the first quarter of the 17th century, considered to be one of Madrid’s first Baroque representatives.  Its façade stands out for its simplicity, broken only by the front.

The church has a single nave, with three sections and niches without a transept.  The main chapel is raised above the general level, the only example of this type conserved in Madrid. Inside, there are various works of art, such as the main altarpiece created by Antón Morales or the painting of the Last Supper, by Vicente Carducho.

The nuns from the convent have a shop, from which they sell a selection of homemade sweets.
