The tower known as Torre dels Ducs de Medinaceli or Torre del Comendador is located in the town of El Verger and, more specifically, in the street called Carrer de L’Abadia. The walls of this tower are the only original existing remains of the palace known as Palau del Marqués de Dénia. As a part of this estate, the tower was erected as a 15-metre-high block of masonry reinforced with ashlars. The tower has a quadrangular floor plan and contains four small rooms.

Its access through the first floor and the scarcity of openings in the façades indicates that it was probably the last defensive stronghold of the palace. Holes are only seen on the third floor, where there are two embrasures, one facing north and the other towards the west. On the fourth floor, there are machicolations (defensive structures on a wall in the form of closed balconies used to defend the accesses to the towers and placed so as to be able to attack a possible intruder from above) on the four faces of the prism, which indicates that at some point it was a free-standing piece not attached to another construction.

The palace seems to have been demolished at the end of the 19th century. The tower, on the other hand, survived, and at the beginning of the 20th century it was purchased by an individual who used it as a transformer tower, a fact that allowed it to be preserved to this day. In the 1990s, the Town Hall of El Verger acquired the remains of the palace and after a long restoration process, which ended in 2007, its value was enhanced. It is currently protected by the Decree of April 22nd, 1949, regarding the Protection of Spanish castles (B.O.E. May 5th, 1949), which globally protects all military architecture.

This tower is the most representative building in the town and the one with the most historical and artistic importance. Currently, it is often used as the setting of interesting shows and exhibitions.
