Although the military uprising initially succeeded in almost all the towns of Los Pedroches, in August 1936 the region came under Republican control and remained so, apart from minor adjustments in border areas, until the end of the war. As a result, the territory preserves many remains from the Spanish Civil War: bunkers, trenches, observation posts and shelters that form part of its recent historical heritage.
Although most of these remains are located on private land, air-raid shelters were built in some towns, and several are preserved in very good condition and can be visited. This is the case of the shelters in El Viso and Villanueva de Córdoba.
Several airfields were established in the region, including those of Hinojosa del Duque and Santa Eufemia, strategic infrastructures for territorial control and logistical support. Around these facilities, various air-raid shelters were built to protect troops and personnel from possible bombing.
The shelter preserved here is one of three built by the Republican side around the perimeter of the airfield located southwest of Santa Eufemia. It is excavated directly into the rock and reinforced with concrete. It has two entrances with steps leading to a vaulted gallery around five metres long. Its state of conservation is very good, although in rainy periods it may flood due to seepage.
Today, these elements are valuable material testimony to that period and invite reflection on a past that left a deep mark on the region.
