January 2, 2026, Ormaiztegi Viaduct

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.

The lords of Igartza built this service center in the 16th century and increased their wealth. This magnificently preserved monumental complex, in addition to the palace-house of the lords, has: a hermitage, a mill, a forge, an apple press, a dovecote, the shoemaker's house and the blacksmith's house, among others. The visit is worth it.

If you like sheep cheese, you are in the right place. Idiazabal is the headquarters of the shepherds' council that brings together the producers of the famous cheese of the same name. Here you can visit the Idiazabal cheese museum and learn much more about this dairy delicacy.

It is well worth visiting these old ovens. It can be done on your own, walking and by stairs.
