Fortifications

Isolated fortifications

Four-sided towers
Circular towers

They seem to be the most frequent. Their presence is generally associated with the evolution of the characteristics of defensive structures consequent on the use of fire arms; however, even older towers like Riccia, Colletorto, S.Croce di Magliano or Roccapipirozzi are not unusual. The construction technique is characterised, in most cases, by the use of mixed stone elements laid in rows that were made level and regular through the use of large quantities of mortar. Semicircular floor-plans were normally adopted in the construction of corner or curtain towers (often escarped) which were frequent features of almost all the settlements of the Aragonese period.
