A small village in the province of Chieti, placed on top of a rocky hill between the river mouth of the river Sangro and the stream Feltrino, Rocca San Giovanni is mentioned for the first time in a document of 1047 of the Emperor Henry III, addressed to the monastery of San Giovanni in Venere. In 1076 the Abbot Oderisio I had the centre fortified to protect the inhabitants of the monks and named it, in fact, Rocca San Giovanni.
Besides the remains of fortifications and the tower, not to miss:
- the Church of St. Matthew, which dates back to 1200, features one major nave and two aisles, divided by lancet arches and a visible roofing. Inside it preserves masterpieces of art such as a fresco depicting "The Last Supper" by Amedeo Trivisonno and a painting of the Madonna and Child by the Byzantine school.
- the Town Hall, built in the XIX century, which features on exhibition an interesting collection of contemporary art.
