Riccia borders the following municipalities: Castelpagano, Castelvetere in Val Fortore, Cercemaggiore, Colle Sannita, Gambatesa, Jelsi, Pietracatella, Tufara.
In the 13th century, Riccia became part of the Monastery St. Pietro e Severo (St. Peter and St. Xavier), located in the nearby town of Torremaggiore.
In 1500, Bartolomeo II De Capua built an elegant castle in Riccia and also restored the church of Santa Maria delle Grazie in Tuscan style, where five feudal lords and their ladies are buried.
In the beginning of this feudal period, the rulers of Riccia, the noble De Capua family, were viewed as fair and generous with the peasants.
After the war, because of the scarcity of work locally, Riccia had a strong outflow of immigration to northern Europe (France, Switzerland, Belgium Germany) and to Latin America (Venezuela and Argentina).
