The study of the plan of old excavations in Numantia allow demarcating the perimeter of a previous occupation, in particular in South zone, reflected in a semicircular extension parallel to a previous city that corresponds to the closing of the wall city of which part of its route is known.The occupied surface approached to 9 hectares that is something bigger than the old city. This second city presents irregular streets in its execution and plan. The streets were paved with stones of uneven size. In the stream there are big raw stones without any regularity which were used as stepping-stone from a sidewalk to another. The planning of this city is the result of the adaptation of the Indigenous initial plan to the following extension and city necessities in the course of the 1st century BC.
