family present in these places in the Middle Ages, but there are many opinions and even legends on the origin of the toponym. One of the most famous is that according to a noble woman traveling in the lost area of jewels including a beautiful and precious necklace. The name "Gioia del Colle" was given to the place where the necklace was found. The complex and original history of the city of Gioia del Colle is also illustrated in its particular heraldic coat of arms: a goblet-shaped cup full of jewels and bordered by agricultural motifs. Unlike the coats of arms of the neighboring countries, that of Gioia del Colle, dating back to 1934, is not linked to any symbol depicting families, marquisates or duchies. It tells the presence of a heterogeneous civilization ranging from poverty to wealth, from crafts to large estates . It is inspired by a sculpture made in 1480 by Joannes de Rocca, on a stone walled in the University of Gioia's seat. It depicts three coats of arms: that of Gioia with the inscription Universitas Joe, the Aragonese one with the royal crown and that of the Acquaviva counts of Conversano. The inhabited area was rebuilt by the Norman Richard of Hauteville, only to be destroyed by William I of Sicily. It was re-founded in 1230 by Frederick II of Swabia on his return from the Crusade. It seems that the castle was a residence where he stopped during his hunting trips. It was then completed by the Angevins who opened windows on the curtain. Between 1600 and 1800 the successive owners (Acquaviva d'Aragona, the De Mari and Donna Maria Emanuela Caracciolo) removed the appearance of a fortified residence from the complex. The "new" city, however, would have originated from a much older settlement: Monte Sannace, about 5 km away from today's town. Archaeological excavations, even today, bring to light the remains of a village of Peucetians dating back to the 7th century BC. Gioia was born during the Byzantine dominion and then passed under the Norman dominion, it was given to Count Richard of Hauteville. Frederick II was responsible for the reconstruction of the castle. It was principality of Taranto and fief of the De Mari princes of Acquaviva delle Fonti until the abolition of feudalism.
