The civic coat of arms of Diso consists of  a lamb in a green lawn with a flag on the right leg. The background is blue. In the territory of this village people found an ancient  menhir where the old populations used to worship their Gods. We do not know exactly how and when the village was founded but we can advance a couple of hypotheses.  It could have been founded by the Greeks after the destruction of Troia. According to Mr Arditi the village was created in the 10^th century when the lords of Castro built some villas in this area because of its climate. The name of the village was Disio. When the Turks invaded the Salento in 1480 and in 1536, those who survived those bloody persecutions, found shelter in Diso and the village became bigger. The name of the village could derive from “dizos”, a messapic word for fortitude.  A third hypothesis is that the village was founded by the Messapi in the 7^th century B.C. and it was a fortified village. until the 12^th century the village was dominated by the Romans, the Byzantines, the Longobards and the Saracens. The village was ruled by Ruggero II, Count of Sicily, the Sangiovannis, the Bielottos, the De Righis, the Sinerchias, the De Francos, the Orsini Del Balzos, the Della Postas, the Gattinaras, the Ruiz De Castros, the Lopez De Zunicas and finally the Rossis. Among the famous people of Diso, we remember: Filippo Bottazzi was born in 1867, he took his degree in medicine in 1893, then became teacher of Physiology in the University of Genoa. He was Rector of the University of Naples, and received an honorary degree from the Catholic University of Milan. He was elected mayor of his village. he was an appreciated scientist and wrote several books. He died in 1941. Giuseppe Bono lived in the 17^th century, he was a missionary Capuchin and had to travel in many foreign countries and wrote several books on Canonic Law.  Pietrantonio Stasi was born in 1839 and was the beloved and esteemed priest of the village. He was Antonio Bottazzi’s friend and spiritual guide and wrote several poems that have been lost. He was a humble and cultured priest and left all he had to the Maternal school of Diso. Paolo De Blasi lived in the 16^th century he belonged to a very rich family but he was attracted by the monastic life so gave his patrimony to build the Convent of the Capuchins. Later he became  monk. Giuseppe Bottazzo was born in 1821 and learned to draw from his uncle, Francesco Saverio Russo.
