 Therefore the designer of the forum took advantage of this wall to create a shrine to water gods, typical in the celtibérian world.In front of the wall, decorated
with rectangular niches and alcoves, shops were built at the foot of the retaining wall.Their roofs served as part of an elongated terrace at a lower floor level of the Forum and divided into two halves, one like a large balcony supporting the retaining wall on the rear and providing a view over all the city, and the other half covered and attached to nymphaeum.
