The pilgrimage along the Way of Saint James constituted the principal mechanism for the introduction of new currents of thought into the Iberian Peninsula, such as Romanesque architecture. Taking this into account, we examined whether the standard tradition on the orientation of Christian churches was followed. We measured the orientation of 108 churches built between the end of the 10th and 13th centuries near the French Way, in the ancient kingdoms of Leon and Castile. The statistical analysis shows a clear tendency to orientate the apse of the church eastwards, specifically slightly to the north of due east. Furthermore, we found that the orientation patterns differ from one kingdom to the other. In Leon, there seems to be a predilection for the local tradition of aligning the apse toward the ecclesiastical equinox. Castile, in contrast, built their churches orientated to Easter, one of the most important feast days of Christianity.
