During the autumn of 2006 eight sondages of different extension were conducted in both walled areas and their surroundings. The main area (C2) was built in emplecton. Its walls, 1/1,20 m high and 1,8/2,50 m wide, enclose a 9,90-ha flattened terraced surface. There is a smaller enclosure (C2a), presenting also a flattened terraced surface, to the southeast of the main walled area.

The aim of the first sondages was to identify the technique used to build the walls and determine the existence of possible ditches. Sondage 1 in C2a enclosure revealed the existence of a destroyed large circular construction. Its dimension and characteristics seem to correspond to those of a building (H1), possibly a of the “tumulus” kind, dating to the late Neolitic era or Bronze era. Iron pegs for tents geometrically arranged were found on the Roman level in both, enclosure C2 and C2a. They are similar to those found in the camps of Numantia (mid-second century BC). During cleanup and systematic survey activities numerous stone projectiles, coins and remains of weapons were recovered, all of them characteristic of Roman military settlements.
