Grumo Appula (Barese: Gréume; Latin: Grumum) is a town and comune of the Metropolitan City of Bari, Apulia, southern Italy.

Pliny likely refers to the inhabitants of Grumo in the Naturalis Historia (105, III), where, listing the peoples of Calabria (as Puglia was called at the time), he mentions the “Grumbestini” alongside the “Palionenses” of Palo del Colle (Palion) and the “Butuntini” of Bitonto (Butuntum).

During this period, the village was included in the fief of Conversano (Bari) and, around the mid-13th century, passed to Goffredo di Montefusco.

Given this, the crescents on Grumo’s coat of arms, in the absence of reliable sources, cannot be definitively attributed to the influence of either group of rulers over the centuries.

The shield is surmounted by a City crown, decorated with golden ornaments, and features two branches—an oak and an olive—tied together with a tricolor ribbon at the bottom.

The morning after the procession in the down, the statue of the Madonna and the carts are taken, accompanied by many faithful, to the hamblet of Melitto, about 9 km from the down centre.

At the end, some men, about 20, in piazza Cardinale Colasuonno, sing the canto del venerdì Santo, an ancient dirge entirely in the grumese dialect, which narrates the passion of Christ.

Significant, is the spiritual presentation of the individual mysteries, which takes place at the exit from the mother church in Corso Umberto after a brief reflection by the parish priest, the delivery of the crucifix in to the hands of the Addolorata takes place, where the wole city flocks to see this intense and significant moment.
