As a symbol of the Franco regime, this set of underground galleries and firing posts were built after the Civil War with slave labour, that is, with the prisoners of the defeated side.<\/p>\n\n\n\n<p>After the European victory of the Allies in World War II, Franco feared that the Allies would overthrow his government by declaring war on him and that is why he built this line of defence. However, the attack never happened.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Construction<\/strong><\/h2>\n\n\n\n<p>In Gorliz, this group consists of several concrete firing posts.

They were prepared to resist an air attack thanks to its concrete structure although finally there was never a need to use them. Their purpose was to form the first line of defense against a possible attack from the north.<\/p>\n\n\n\n<p>From the highest point of the batteries at Cape Billao and at high altitude above sea level, one could control the aerial and maritime landscape and also see Billao Island.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Routes<\/h2>\n\n\n\n<div class=\"wp-block-genesis-blocks-gb-columns gb-layout-columns-3 gb-3-col-equal\"><div class=\"gb-layout-column-wrap gb-block-layout-column-gap-2 gb-is-responsive-column\">\n<div class=\"wp-block-genesis-blocks-gb-column gb-block-layout-column\"><div class=\"gb-block-layout-column-inner\">\n<figure class=\"wp-block-image size-full has-custom-border is-style-image-image-zoom\"><img decoding=\"async\" width=\"500\" height=\"300\" data-src=\"https:\/\/www.visitgorliz.eus\/wp-content\/uploads\/2023\/03\/NW_rutaakosta_01-1.jpg\" alt=\"View of Billao Island from the cliffs\" class=\"wp-image-25013 lazyload\" style=\"--smush-placeholder-width: 500px; --smush-placeholder-aspect-ratio: 500\/300;border-width:2px;border-radius:5px\" data-srcset=\"https:\/\/www.visitgorliz.eus\/wp-content\/uploads\/2023\/03\/NW_rutaakosta_01-1.jpg 500w, https:\/\/www.visitgorliz.eus\/wp-content\/uploads\/2023\/03\/NW_rutaakosta_01-1-300x180.jpg 300w\" data-sizes=\"(max-width: 500px) 100vw, 500px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">ROUTE TO BUNKERS INLAND<\/h3>\n\n\n\n<p>Distance:&nbsp;<strong>6.1 km<\/strong>, Time<strong>: 1:40 hrs<\/strong>, Climb:&nbsp;<strong>287&nbsp;m<\/strong>., Category:&nbsp;<strong>Demanding&nbsp;<\/strong><\/p>\n\n\n\n<p>This interesting and easy route explores the different areas between Astondo and Cape Billano.

It is well over 30 km and takes just over 7 hours to complete, with a cumulative elevation gain of almost 900 m, which, bearing in mind that it runs through this area of Uribe Kosta where there are hardly any large mountains, is a big deal. It is a typical \u201cleg breaker\u201d, recommended only for experienced people who are used to several hours of walking. Of course, another option is to do the route in two days, dividing it into two stages. Doing that makes the challenge a little more manageable.<\/p>\n\n\n\n<p><strong>Total time: 7 hours 30 min.<\/strong><br><strong>Distance: 34 km<\/strong><br><strong>Cumulative elevation gain: 900 m<\/strong><br><strong>Difficulty: High<\/strong><\/p>\n\n\n\n<p><strong><a href=\"https:\/\/www.visitgorliz.eus\/en\/route-19\/\">More info<\/a><\/strong><\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-genesis-blocks-gb-column gb-block-layout-column\"><div class=\"gb-block-layout-column-inner\">\n<figure class=\"wp-block-image size-full has-custom-border is-style-image-image-zoom\"><img decoding=\"async\" width=\"500\" height=\"300\" data-src=\"https:\/\/www.visitgorliz.eus\/wp-content\/uploads\/2023\/03\/Ruta_20.jpg\" alt=\"Cliffs of Gorliz and Lemoiz in a day with clouds\" class=\"wp-image-25247 lazyload\" style=\"--smush-placeholder-width: 500px; --smush-placeholder-aspect-ratio: 500\/300;border-width:2px;border-radius:5px\" data-srcset=\"https:\/\/www.visitgorliz.eus\/wp-content\/uploads\/2023\/03\/Ruta_20.jpg 500w, https:\/\/www.visitgorliz.eus\/wp-content\/uploads\/2023\/03\/Ruta_20-300x180.jpg 300w\" data-sizes=\"(max-width: 500px) 100vw, 500px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/figure>\n\n\n\n<p><strong>The seven small peaks from Astondo to Armintza<\/strong><\/p>\n\n\n\n<p>This is a route for the brave, for experienced mountain people who don\u2019t mind suffering for a while crossing relatively difficult stretches at the expense of having at almost all times spectacular views in areas very little frequented.
