About 1500 grottagliesi went to work at the Italsider, There were already about 5000 people working in this great industry. Under the social aspect, Grottaglie the farm was free, where he lived between road, casa e piazza. The road was a continuation of the house, and the square was the meeting place. The joy of the neighborhood was the delight of all, the pain was the pain of a family in the neighborhood. If a child was born it was a joy for all, if there was a disease or death was a pain for all. There was this great sense of provincial cities, we dove era solidarity. In 1960 Grottaglie entered a donation, that Robert Guiscard, Mensa granted to the Archbishop of Taranto, to thank the Pope for favors received. Therefore, Grottaglie was no longer a city but by the secular 1960 became an episcopal city. In fact, Castle which is still the symbol of power, is a castle Episcopio, because the rule is that belonged to the Bishop, who resided six months and six months in Grottaglie Taranto. In the castle there is also a garden dedicated to him (Il Giardino di Giacomo D'Atri). Instead, in Piazza Regina Margherita is the Palazzo Cicinelli.
