The current pharos was built between 1854 and eighteen hundred and fifty five on the slopes of Mount Igueldo and is situated at an altitude of 134 meters supra ocean level. Its inaugural light was developed with oil and paraffin. In nineteen hundred and sixteen alterations were presented to induce it work with oil. In nineteen hundred and eighteen it became electrified, in 1912 the township of Igueldo accredited the designer Luis Elizalde refurbishments, incorporating a plant with expectant windows and a patio (from it you can see the city of San Sebastian and the landscape), and in 1929 his flasher was renewed, expanding its range.
