The area has been inhabited since antiquity; nearby archaeological sites, notably the ancient Roman town of Alsium, attest to a long history of settlement along this stretch of the coast. Over the centuries, Montalto di Castro was part of the Papal States until the unification of Italy in the 19th century.
