On the origins of the town's name, there is no agreement: one school of thought attests that it derives from the personal name "Morico", another from the presence, in ancient times, of a family of Moors, that built a fortified settlement nearby, and finally one that attribute the meaning of Morro to the surrounding rocky ground. Municipality in the province of Fermo, it is a tiny village surrounded by large XIV century fortified walls and two large gateway entrances, one of which is inserted in the clock tower, while the other ends in the main square marked by great harmony. The town, dominated by a watch tower of the XII century, is situated on a ridge covered with lawns overlooking the Valley of Aso.
On the origins of the village, there is not much news: it was probably founded around the year 1000, period in which its presence was first documented. In Roman times, several important settlements were built in the territory of Moresco. In the XII century, the town was ruled by Theobald, Count of Moresco, who later ceded the domain to the nearby city of Fermo. Once free from feudal rights, Moresco became a municipality and maintained that status until 1869, when it became a district of Monterubbiano. It returned to be autonomous in 1910.
