Optical telegraphy tower, built in the middle of the 19th century, no. 47 of the line from Catalonia to Valencia. It is located on top of a hill, at the beginning of “Les Guàrdies”. From the top there are beautiful views of the coast, from Cape Salou to the Ebro delta. How to arrive? It is accessed through the south entrance of Perelló, where we will find a roundabout and, a few meters away, we will see the sign on the right. From here, a paved path of 1.5 km will take us to the tower.
