The Unpublished Drawings of the San Acasio Building (Seville) of the Architect Marrón y Ranero

This paper aims to present in heritage, typology and urban terms a little known work in Seville, promoted in the nineteenth century by the Marquis of Guadalcazar and designed by the architect Balbino Marron y Ranero. The passage building, which is still preserved, though with alterations, is located in the commercial area of the historic centre and connected the streets of Sierpes, O’Donnel and San Acasio, on the site of the current Pedro Caravaca street. On the plot different proposals were followed, the first at the end of the 18th century by the architect Felix Caraza. During the first and second thirds of the 19th century, the projects taken on by several architects (Melchor Cano, Manuel Galiano and Balbino Marron y Ranero) maintained different approaches as to how to intervene. The last project, presented here, was devised by the municipal architect and architect of the Dukes of Montpensier, Marron y Ranero. His unpublished drawings have allowed us to reconstruct the history of the project on this site: a unique contribution to the urban heritage of Seville that reflects a way of intervening in the city that can no longer be considered romantic, but one that anticipate a fully modern professional practice.
