Between the 13th and 14th centuries, the hamlet of Calp was fortified by walls in order to protect it from Muslim attacks. Its coastal location made its population vulnerable to constant pirate attacks, due to which, in the 16th century, Carlos V ordered the repair of the walls. The neighbours could access the citadel through only one entrance gate, called El Portalet.

The most serious attack was the one that took place in 1637. The Barbary pirates invaded the town without being noticed beforehand. The guards were asleep and the pirates went up the walls using ladders. During this attack, they took captive almost all of the inhabitants of Calp.

Another important attack —which gave rise to its patron Saint festivities— was the one on October 22nd, 1744. After that pirate attack, a project started, aimed at fortifying the town, and a second wall was built which surrounded the suburb and the old citadel. The Torreó de La Peça takes its name from a piece of artillery hidden in the tower, which was demolished in the 20th century.

The Torreó de La Peça tower structure has left behind some very interesting remains of military architecture of the fortress. During 1947, the Town Hall ordered the demolition of the La Peça, uncovering the Torreó or Tower, the existence of which was unknown.

The tower has a truncated cone shaped base, but its upper part is cylindrical. It is made of mortar-joined stone.

Nowadays, if one is in the area of Calp, the place is worth visiting. It is in a good condition due to the fact that, in 1981, both the walls and the tower were restored. Its interior houses the Collectionist Museum (Museu del Col·leccionisme). Additionally, two cannons of English manufacture can be found next to the tower, dating back to the 18th century. They were pulled out from the port of Calp. (1)
