This paper presents some of the information obtained during the archaeological surveys carried out in 2019 in the stately fortress known as Torre de Isso, located in the municipality of Hellín (Albacete). These fieldworks have attempted to answer some questions related to the historical interpretation of the preserved monumental remains, specifically two large towers and some walls from the second half of the thirteenth or fourteenth century.
This study addressed the historical phenomenon known as incastellamento, in the area of the current province of Viterbo, from a quantitative and geographical perspective. The time period considered was the 10th-15th century. The paper describes the documentary sources, historical maps, aerial images, past studies and archaeological sources that are available to researchers, and which have been used, in good measure, to reconstruct the fortified settlement network.
