Referred to in the archival documents as “Torre ubi dicitur la Pagliarola, tower in maritime constructa vel in maritime Castri Abatis, Tower of the Marina of the Castello dello Abate, and finally Torre Perrotti”, it was built, under royal direction, in the first half of the century XV, near the ancient medieval port of “lu Traviersu”, in the ancient and homonymous locality of Pagliarola, a vast flat area bordered by the sea and the slopes of Monte Sant'Angelo, on which the Castello dell'Abate was built.

After the fall of the Sanseverinos, the Tower passed into the hands of various powerful families of feudal lords (Caracciolo, Carafa, Freccia, Filomarino) to be definitively requisitioned by the Royal Court, because it was considered indispensable for the control of commercial traffic and the defense of the coast from the attacks of the Turks.
