of his sins. These indulgences were conceded by Pope Pius IV in the year 1564 by request of D. Álvaro de Castro, being Ambassador of Rome" The presbytery is marked by the vestiges of a wooden balustrade and covered by the rocks that conceal the space. The church walls include fascia inscribed on the rocks and a concave retable in marble, crowned by cornices. The central axis includes three panels: the central panel, including the tabernacle framed by pilasters and flanked by two niches, and the lateral oblique panels, which also have a niche. The main altar, in polychromatic marble front, is designed with organic composition. On the pulpit side, there is a small staircase in rock, with access to the choir, itself covered in cork. The space is illuminated by two small windows, with two bunks of seating, also covered in cork, where the friars participated in masses. The interior dependencies are aligned along several corridors within the complex and broken by small steps formed by the slopes on which the convent was built. Many of the spaces are covered in cork, which acted as an insulator; many of the doors and windows are covered in cork, while the austere floor is composed of stone slabs. The personal quarters of the friars, eight in total, are small in size with small entrance-ways and access to the main corridor. Friar António da Piedade, writing in 1728, described the cells as so small that a few of the monks carved out portions of the wall in order to accommodate their feet. The refectory included a large slab that was ordered extracted from the mountains by Henry, King of Portugal and used as a table by the monks, and small cupboard. The relatively small space was connected to the kitchen, with stone and chimney, and rock bunks for counters and spaces carved into the rock. The Casa das Águas ("House of the Waters"), accessible through an exterior corridor to a cistern and spring, was the collection and distribution space for water into the convent, and included a water tank, latrines, and urinal. In addition, the complex included a space for novices; an old library with roof covered in cork; an infirmary; hall of penitence; two cells covered in wood; a space for solitude/retreat (located at the highest point in the complex); and the circular Casa do Capítulo, whose access door and walls
