Written sources of the kingdoms of Castile-Leon describing processions and royal entries in the 11th-13th Centuries are not commonly found. The absence of such ceremonies makes it difficult to recognize the topography of power through remarkable buildings as well as the hierarchies among their ecclesiastical and secular participants. This absence prevented the kings of Castile and Leon from being seen publicly and visiting some iconic processional spots which provided the right atmosphere for the most solemn rituals in a medieval monarch’s life. King Alfonso VI’s entry into Toledo in 1085 set a new precedent put into practice by his successors during the Christian conquests of al-Andalus cities, which took place until the mid-13th Century. The transformation of the congregational mosques in the conquered cities provided a unique opportunity for victorious monarchs to display their power through the appropriation of urban spaces. The king’s central role in the ecclesiastical rituals of purification and the subsequent control over the fate of the most representative buildings allow these processions to be considered as spatial and ritual phenomena.
