To facilitate the entry of ships in the northern channel of the A Coruña estuary had used as a reference the light of the lighthouse of Prioriño Cape, too far away to effectively accomplish this mission.
Engineer Salvador López Miño is commissioned to design the lighthouse of Oza in 1908.
Its location in the considered port of A Coruña allowed to elevate the luminous focus 14 m above sea level, in order that the ships avoided the low of the Yacentes and the restinga del Seixo.
The light of the lighthouse began to operate in August of 1917. It was reformed in 1932 to give a reach of 15 miles and greater intensity.
This line was replaced in 1955 by a new one located in Punta Fieiteira because the works of the shelter dam and the consequent variation in the course of entry of the ships in the port invalidated its function. The new range has a range of 3 miles.
In this way in 1963 the service of the lighthouse of Oza is suspended.
Curiosities, myths and legends
As a consequence of the observation of infectious-contagious diseases in 1403 the first lazareto is established on an island near Venice.
The lazareto was defined as a sealing space near the sea and expressly built to receive merchandise and patients during the quarantine that was imposed on them. A place was set away from the city and the port, the "suspects" stayed 30 days in the open air and in the sun, so at first it was called "trentina". As the period was short and insufficient it was extended to 40 days and was called "quarantine".
During the s. XVIII the State intervened for the control of public health so that the lazaretos spread throughout Europe.
In Spain there are in the s. The two important ones, Mahón and Vigo, as well as Pedrosa in Santander, Gando in Gran Canaria and Oza in A Coruña, regulated by the Health Act published in 1855.
