In the words of León y Castillo
La luz del faro “The lighthouse beam “which soars above the dunes due to its height, will have a range of visibility as far as Punta de Juan Grande to the NE, 19º East, and Punta de Taozo (Tauro) to the West, 19º NW, in an arc of 216º”. The plans of León y Castillo included the description of the site of the building: “an esplanade 35 metres wide and 36.5 long will be the site for a rectangular house with a façade of 20.5 metres facing the sea and inland, and sides measuring 19 metres. The tower, circular, whose centre will be placed on the front or façade toward the sea, shall have a minimum radius of 4.06 metres, such that the diameter shall occupy 8.12 metres of the width of this façade, leaving 6.19 metres on each side for the house”.
“The tower and the house thus form a single building that must be designed in the right proportions to create a harmonious whole. This means that the house, which forms the base of the tower, must have an elevation in proportion to its height, a circumstance that requires it to have two floors… The need for two floors, or at least their appropriateness, is recommended as an artistic criterion”.
The tower is a truncated cone rising on the south side of the building, next to the sea. It is built from blue quarry stone, in the same material used to ornament the façade of the building. The decorative stonework of the façade of the keeper’s house continues in the tower (base, fascia and cornice, and torus moulding highlighted by decorative rings in three sizes). The design, with a traditional shaft, decreases in size as it reaches the capital, which is also finished off with decorative rings and corbels.
