This book brings together a wide series of photographs that travel through unknown times and places in the Salon de Reinos, the former Army Museum in Madrid. The images of Alvaro Perdices constitute an archive and visual device that reveals the corners, the absences, the shields without weapons, the empty showcases, the reflection of the intruders or the feasts that have gathered in the remains of the old palace of Felipe IV. The approaches of this art and archive project delve into the ruptures and changes of this state building and its symbols over time. Texts by Juan Herreros, Maria Virginia Jaua, Maria Dolores Jimenez-Blanco, Manolo Laguillo, Alvaro Perdices and Manuel Segade. In co-edition with the CA2M, Centro de Arte Dos de Mayo, Madrid. Text in English and Spanish.
