This area was a mining complex, the Mutiloa mining district, from the late 19th century. In 1911, 162 miners worked there, and in 1912, 34,500 tons of iron ore were stored and washed. After being transported by rail to Ormaiztegi, it was shipped to European steelworks. (https://www.mutiloakomeatzaritza.eus/es/la-via-verde/)

The Ormaiztegi Viaduct (inaugurated on August 15, 1864) is the town's most emblematic symbol. Designed by engineer Alexander Lavalley, a predecessor of Gustave Eiffel, it stands in a beautiful landscape overlooking the Eztanda River. It is the most important structure on the Madrid-Paris railway line, spanning 289 meters in length and 34 meters in height. Its 18,000 tons are supported by four pillars. The double track was installed in 1912 and electrified in 1928. It is currently disused and forms part of the Basque Country's cultural heritage.

That bridge is called "INTUIA-ko zubia" the INTUIA farmhouse is next to it. The misnamed "witches' bridge" is called UNANIBI-ko zubia, right in the Otita park (beginning of the Leitzaran valley). Don't forget to bring lights to cross the numerous tunnels in this valley!! Not to see but to be seen.

The beautiful building of the old Urola de Azcoitia train station is currently used as a library. One of its rooms is decorated with old railway sleepers. In the back there is a bike mechanic and washing station.
