The complex of the Masseria Fortificata Spina (XI-XVIII century) lies within an area where nature, archeology and architecture found a bond so strong that individual emergencies, as a product of a typical micro history, reveal themselvs so linked between them that they form a single landscape; indeed, a wonderful balance between the natural elements and cultural evidences developed, a balance so prosperous of man-made signs, some of them observable and valuable during guided tours of the different underground, where various traces are spotted, like housing, manufacturing and religious ones, and others, stronger and more incisive, such as the Via Traiana trail, the villa rustica and the tower. The compound is characterized by the presence of many caves (most of them seeable and intended for different uses in ancient times) and some tanks; still, its peculiarity is the architecture of the Spina Piccola tower, with its surrounding wall and the main body of Spina Grande, with the adjacent church dedicated to Madonna Immacolata.
