The route does a circular trail along the Oleiros coast, beginning in the village of Mere, near of the lagoon with the same name. From this place you will arrive to Punta de Mera, where some interesting lighthouses stand. At the same time, it finds in this zone the ancient house of thelighthouse keeper, transformed at present in a Reception of Visitors Centre and in a “Aula do Mar” (Sea Classroom), that display the Dexo-Serantes Coast valuable things, catalogued like Natural Monument. The path continues along most of this protected space, standing out the strength and the beauty of its cliffs. In the vicinity of ‘O Seixo Branco’ appear a series of furnas and bufadoiros (rock cracks) that were carved out of rocks by the sea. From the coast, you can see a series of beautiful islets, standing out between them A Marola.
From ‘O Seixo Branco’ we arrive to Subiña, Punta Roza and Torrella old settlements, and to Santa María de Dexo, a Romanesque church built in the 12th century. A little further ahead we find the Lorbé port, an aquaculture production area, where you can taste the typical mussels.
And from Lorbé, we walk to Maianca to visit the pre-Romanesque church and its mills. After this stop on the way, we arrive again to Mera, starting point and ending of the route.
The minor deeper draught ships that head to A Coruña take the channel of Punta Herminia and are headed to the port when they reach to see the lights of the two lighthouses of Mera making a line. These two towers of maritime signals celebrate this year its 100th anniversary and continue to operate guiding to the sailors and prevent the risk of the sandy shoals of the estuary and of the rocks, especially those with sharp edges and points. The Mayor of Oleiros, Ángel García Seoane, announced last week that between his projects for 2017 it is planned the publication of an Anniversary Book in memory of the lighthouses, and that he commissioned his ex Councillor for Town Planning & Development, Daniel Romero, a great connoisseur of its History, to take care of it.
The lighthouses were built in 1917, although its torches were light up for the first time one year later. They were erected at the same time as the lighthouse of Oza, all of them inside a project directed by the engineer Salvador López Miño with the purpose of facilitating entry into A Coruña port and safeguard against the dangerous shoals of Xacentes sandbank.
Although called lighthouses, they are two transit control towers that function also as signalling and lighting system for the buoy-marked zone. In its beginnings they were lighted by civil servants with filament oil-steam lamps produced by the company Julius Pintsch (Berlin), but in 1932 it was installed an electrical system visible from about eight miles.
The so-called ‘Pequeno’ (‘Small) lighthouse, the one that is at the edge of the cliffs, is eleven metres high and emits a white and red light. The another one, which is located further ashore, is the big lighthouse, fourteen metres high and white light. The smallest is the most visited by the impressive views of all A Coruña bay. Their structure is similar, octagonal and with terraces in the headlamp cover decorated with a lattice balustrade and polygonal torches.
Between the two towers was built a house for the lighthouse keeper with only one floor and letter T shape. Many of the lighthouse keepers are still remembered today in Oleiros because they also worked as school-teachers (forbidden to them) and a lot of neighbours went to their school, more liberal than the education of the period. In 1999, the Town Council signed an agreement with the Port Authority to hand over them free the lighthouses and the house of the lighthouse keeper for five years, extendable for one more year, and in 2002 local authorities ordered to rehabilitate the house as an Environmental Interpretation Centre of the Coast of Dexo-Serantes Monument. Nowadays this house is a Visitors’ Reception Centre and “Aula do Mar” (Marine Classroom), and the Ceida is responsible for plannig the guided visits. Inside it you can see the ancient torches of the lighthouse and reproductions of mussels farms and of one furna.
