This intervention is the result of an archaeological supervision of the works of the cable installation in the old town of Villena. In the first place, we dugtrenches ditches of 35 cm wide, and later, 20 cm wide. The layout of the ditches has usually followed the sides of each one of the streets, just right on the sidewalk, and in the intersections of these streets we have often used a catch basin. We have subdivided the area subject to archaeological intervention in sections delimited by berms. Their purpose was to try to establish an order in the and to place each of the archaeological materials recovered on their rightful place, measured to the millimetre. That way, a section is defined as the space between two of the berms. From this archaeological monitoring, the following discoveries stand out: - A series of paved streets related to the 20th century (SUs 10003, 11003, 11005, 16001, 17001, 19001, 21001 and 22003), as well as a series of pavements of streets, made up of tamped sand mixed with lime, that date back to the 16th and 19th century. All of this seems to denote a fossilization of the Late Roman Empire urban layout, with respect to the one that is conserved nowadays. The streets usually appear directly over the geological base, what would confirm the durability throughout time since its urbanization. We have only distinguished some levels of occupation from the Late Roman Empire and the Modern Era (SUs 2100, 7101, 10002, 10005, 10100, 11100, 19003, 19004, 19005, 21004, 22101, 22102 and 22103.) There were no walls within the trenches, which confirms the proposed hypothesis. - There has been no documentation of any new section of the fortification wall, despite of having excavated trenches in the streets in which they should have shown up (José Zapater Street, Maestro Caravaca Street and one more). However, what we have discovered is the tapial construction on many houses that still stand, such as the one in Empedrada Street and one new in Nueva Street. - A complex network of irrigation systems and underground channels, or qanats, throughout the Old town of Villena has been documented. Its starting point is located in Rambla Chonga Street and extends towards the Main Square, passing through its lower part, San Antón Street, Teniente Hernández Menor Street and Mayor Street. Its layout has not been altered by the trenches and, thanks to them, we have documented three ventilation shaft of this irrigation channel. One of them was in San Antón Street; another, in Teniente Hernández Menor Street; and the last one, on Mayor Street. - Three subterranean passages, which cut perpendicularly underground the main axis of Teniente Hernández Menor Street, have also appeared. All of them follow an east-west direction and their dimensions are deep (a mean of 2.5 metres deep) and narrow (between 1 and 1.5 m wide.) The ceramic material eases the documentation of the existence of three cultural and chronological horizons, which are clearly differentiated. In the first place, we have recorded the presence of materials from the 14th and 15th centuries, such as the case of green-purple-decorated pottery and cobalt blue pottery in strata related to the occupation. In the second place, a large set of pottery with metallic lustre from the late of the 16th century and the 17th century which belonged to the pavements of the streets, along with manganese painted pottery, has been found. In the third place, a series of blue ceramics decorated with vegetal patterns from the 19th and 20th century from Bihar appeared. And last, there is a series of drag materials or secondary sediments (2 fragments with no shape of painted Iberian pottery from the 2nd century and one fragment of handmade pottery scrap from the 3rd and 2nd millennium BC).
