El asedio de Alcalá la Vieja (1118) a través de los proyectiles de piedra: un estudio interdisciplinar

The castle of Alcala la Vieja (Alcala de Henares) has been the case study in numerous investigations since the eighties, but the siege —which took place in 1118— has remained forgotten. Due to the discovery of four stone projectiles in 2017, we have carried out several works to widen the knowledge about this historical fact, and also to fill some existing gaps. For this task, we opted for proposing an interdisciplinary study: combining archaeological and historical data with physical calculations and spatial analyses. The amalgamation of different research areas has served to fix a series of documentary problems found in written sources; this would not have been possible following only a standard methodology based on historical and archaeological information.
