Abstract

This research studies the mineral composition characterization and internal texture of selected mortars collected from the church of San Pedro Apóstol of Polvoranca (Leganés, Madrid). The aim of the survey is to provide as much additional information as possible through the archaeological investigation so as to achieve a better understanding of the remains and to establish the chronology of the archaeological group. The church, founded in medieval times, suffered an important reformation during the 17th century directed by the architect José de Villarreal. The temple is one of the best examples of Barroque architecture made of brick masonry –with the use of gypsum mortar joints— preserved in the area of Madrid. The analysis of mortars helps in establishing a construction chronology differentiating medieval and modern phases of the church architecture allowing for a better interpretation and understanding of the remains of this interesting built group.
