The civic coat of arms of Giurdignano has a blue background and it represents  the letter "G" surmounted by a hat. The origins of this village are ancient, in fact, there are a lot of megalithic monuments on the territory, above all menhirs such as the menhir "San Paolo" and the twin menhirs. "San Paolo" menhir is situated on a cave in which there is a very beautiful fresco representing  the saint. The most interesting dolmens are the "Stabile" that was probably was  used as altar for ancient rites, and the twin dolmens denominated "Grassi". Many other megalithic monuments cannot be visited since they are situated in private residences built before the first half of the XX century. The presence of so many dolmens and menhirs proves the human presence during the prehistory. Also the toponym is ancient; in fact, Giurdignano is a Messapian word of song of war  that was sung before each battle. As the origins of this village are concerned there are no  historical documents , but only some theories. Some historians advocate that the first centre was founded by the people who had escaped from the destruction of the neighbouring casali. According to another more probable hypothesis Giurdignano was in the ancient past a small frazione of Otranto, in which there was a strengthened castle where the Roman soldiers used to spend the winter. The feudal age began after the arrival of the Normans when the king  Tancredi  of Altavilla asked  Niccolò De Noha to rule this centre. The other feudal vassals were the  Alfarano Capeces, that governed Giurdignano until  1806. Among the most important native people there are  Angelo Lanzilao and  Antonio Alfarano Capece. The latter lived in the XVIII century and was a descendant of the noble family that governed Giurdignano for a long time. He helped to improve the social and economic conditions of his own small town. Angelo Lanzilao  lived between the XIX and the XX centuries and after graduating in Law, he became an appreciated lawyer. He died  as a hero during the First World War.
