Archaeological site of Codo Nature · Codo, Campo de Belchite, Zaragoza Image of Codo, not of the place itself. The archaeological site of Codo, in the Campo de Belchite, corresponds to a Visigothic necropolis of the 6th and 7th centuries located in the Varella Castellar area, where burials with modest bronze, ceramic and glass grave goods have been found. The municipality was also the scene of the Civil War: on 24 August 1937 it suffered an attack by Republican troops in the battle of the Tercio de Montserrat, in which the unit, of about 182 men, had more than 140 dead. Belchite fell shortly afterwards, on 6 September 1937, and the civilian population was evacuated on Christmas Eve of that year to refugee camps in the Bajo Aragón. Both episodes form part of the Civil War routes that run through the municipality today. Photo: Dd1495 (CC0) What to see and do in Codo
