St Martin’s tower was constructed during the golden age of Mudejar art, at the end of the 14th century. In spite of the Christians’ early conquest of the Aragon region, from the end of the 11th century to the mid-12th century, (1096 Huesca, 1118 Saragossa, 1120 Calatayud…) Mudejar art remains very present. After the Christian occupation, the early structures built were strongly influenced by Western European art, which was principally Romanesque with a strong French influence. After this first phase however, Mudejar art imposed itself in the region, partly because of a lack of stone but also due to the shortage in manpower capable of cutting stone. The area had a great supply of clay and plaster and it was these materials in the form of brick, ceramic, and plaster that were used to build most of the Mudejar constructions.
