Once the runways were constructed, they noticed the need to install the necessary equipment for the normal operation of the aviation field.Flight offices, maintenance premises, communication systems, accommodation and shelters. They were placed in new construction buildings, in buildings that were already constructed, and in provisional barrack huts that were dismantled when the war ended.Â Â Â Â Â Â Â Â Main building: it was the offices building located in the Southwest part of the field, occupying a rectangle 30m long by 15m wide, in the entry by the Ulldecona road. It is a construction of a very good quality, with stone walls and building works. As an ornamental characteristic, it had the emblem of the republican aviation in the four main corners of the house. The building was perfectly equipped with electric light, a cistern that provided current water and very luminous rooms thanks to the large windows all around. A great terrace allowed having tables and chairs outside. Attached to this building, we can find the shelter in two entrances, one in the Southeast part, and the other one in the Northeast part. The two entrances to access the shelter are separated by about 50 m.
Transmissions hut (Roe House): Making use of a country house located in the Northeast of the field, the necessary works were made to adequate it as a transmissions hut; communication radios and a teletype were installed. The teletype was the most important transmission tool in those times because it allowed transmitting all messages in writing, and communicating effectively in the different air bases of the area. From the beginning, tri-phase alternating current was installed in the entire field, according to the reports of the time.
Maintenance premises: about fifty metres west from the main building, making use of a country house, which was modified as a premises, placing two big doors which allowed to take in and out aeroplane parts and tools.Â
Â Â Â Â Â Â Â Â Shelters: around the field, up to three more shelters were constructed, located to the north of the field, which were used to protect people in case of bombings. The three shelters were perfectly located according to the patterns of the time; there are currently no remains.
Prefabricated premises: mostly in the German period, some wooden barrack huts were built, which were completely dismantled when the field was abandoned.
Accommodation for Officers and for the Troop: the field had no buildings to accommodate personnel, but about 3 km to the east of the field, we find the building called âcuevas de MartÃâ. It is a building in the form of a castle, which was subject to the necessary alterations to accommodate the officers, usually those that were on guard, in case they had to fly quickly. To the south of the field, on the other side of the river Senia, was the magnificent building of the mill-hospital, where alterations were also made to be able to accommodate personnel. The rest of the troop was accommodated in canvas tents around the entire field.
Anti-aircraft defences: Anti-aircraft defences were not installed in the republican period, but they were installed in the German period. Around the aviation field, there were anti-aircraft defences, which were artillery pieces of different types, such as: Flak 36 and the 8.8 mm. batteries. The German artillery unit was called F/88.
