The tower, 12 meters high, was inaugurated in 1883 where there was an older one behind the medieval walls of the village. It has a facade in colored bricks of Molfetta and travertine marble and is decorated with two panels, while on the top there is a statue of the Madonna.
As part of the dispute between the Angevins and Aragonese for the conquest of the kingdom of Naples, the Aragonese sovereign, Ferrante I of Aragon, on 21 July 1462 besieged the town. Despite the brave resistance of the Akkadians, Ferrante managed to take the village and set it on fire. This event, with a faithful reproduction of Accadia of the time, is depicted in two panels in the bronze door preserved in the Maschio Angioino of Naples, precisely because of the will of King Ferrante who was struck by the tenacity of the Accadiesi.A bas-relief inserted in the fake triumphal arch of the tower of Accadia, the work of the sculptor Giuseppe Renda (1859-1939), is, in fact, a reproduction of the bronze door panel of Maschio Angioino. Below the bas-relief is a couplet by Giovanni Pontano, read by prominent Neapolitan humanist and prime minister of Ferrante I of Aragon: "Aquadiam Fortem Cepit Rex Fortior Urbem Andegavos Pellens Viribus Eximiis" (of the fort Accadia an even stronger man took the city, driving out the Angevins despite their large militia).
