Fons Mirabilis

The description provided in the Liber Sancti Iacobi identifies the Fons Mirabilis as the fountain that was in the atrium of the Paradise Door. It was large and had a bronze column in the center, at the top of which were 4 lions' heads from which the water emerged.

It is worth noting that the imagery and symbolism of the Paradise Door, which Archbishop Gelmírez based on St Peter's Holy Door in Rome, extended beyond the doorway itself. The fountain would become a focal point at the end of the route, in a square which, as well as being the site of several religious feasts, was a place where many commercial and pilgrimage-related activities took place.

This stone cup was traditionally associated with the fountain. It is a relic of its time and can also be used to calculate the dimensions of the northern door, which has now been completely renovated.
