This tower is declared a cultural asset of national interest. Historically it was the strategic point for the control of the fluvial traffic.
At this point where the rocker advances towards the Ebre river while the quaternary terrace is removed leaving way, at his feet, in the clay soils, the small hill is located where the tower of the Carrova rises. On the other side of the river we can see, at this height, the tower of Campredó.
The lands around the Ebre river axis housed a complex military defensive and surveillance network formed by towers and castles, on both sides of the river, which would have its origin in Andalusian times (s. IX-XI).
The Carrova also forms part of this net, although the imposing current tower was built in the 14th century, in the limits of the initial domain of the hospitallers in Amposta. The area also shows remains of Neolithic, Iberian and Roman occupations.
During the Middle Ages the estate, in addition to performing defensive functions and participating in war actions by means of the tower, as its role in the war against John II (1465), functioned as an important agricultural farm where wheat, olive trees, vineyards and garden products were grown, and at first, the existence of an oil mill (destroyed in the early fifteenth century) allowed the transformation of the product. The Cistercian community maintained its dominion over the Carrova until the 19th century when, due to the confiscation, the tower became the property of the Marquis of Santa María.
In 1977 the tower was declared a Historic-Artistic Monument of Local Interest with registration number R-I-51-5017. In addition, it subsequently obtained protection as a Cultural Asset of National Interest in the generic declaration of castles and defensive elements of the Spanish Historical Heritage Law (1985) and the Catalan Cultural Heritage Law (1993). The tower, owned by the Amposta City Council, was restored in the 1990s.
