Pilar de la Horadada, which in turn has a total population of 22.967 according the National Statistics Institute. Both of these towns are located in the most southern point of the Alicante province in the southeast of Spain and therefore shares a border with the province of Murcia. The name of the town has its origin in two factors: the first, the 16th century watchtower; and the second, the site where the tower is found: the point of Horadada (el horadada) which comes from the Spanish word for "bore through" as it is situated on rocks made up of small caves developed by the water boring the rock. In ancient times, the Mediterranean coast and specifically the Horadada fields suffered many pirate raids. In order to prevent this, Phillip II had a series of watchtowers built along the coast, so that they could alert villagers about the presence of pirate ships. The Horadada tower was built in 1580, although there are traces of the existence of similar constructions from ancient times and the Middle Ages. From 1905 until the present day it has been property of the counts of Roche, who transformed it into their summer residence. During the 19th century the tower was used to make signals with an optical telegraph. In December 1995 it was registered as a property of cultural significance within Spain’s Historical Heritage as a monument. It is very well linked to the Airports of San Javier (15 km) and Alicante (60 km) on the A7, and has several shopping centers nearby, as Zenia Boulevard or Dos Mares.
