Santa Maria de Eunate A modest little church, yet shrouded in mystery and of rare elegance and harmony. On the Camino de Santiago in the hills lies the octagonal church with a small apse, built in the 12th century. Around it runs an also octagonal arcaded gallery with pillars and double columns. The whole complex is surrounded by a wall. The purpose of this gallery is not yet clear today. Outside the walls, graves of pilgrims with scallop shells were found, which suggests that it was also a cemetery chapel. A document also mentions a hospital of the Order of St. John, which is said to have been located in the vicinity. A legend also tells that it is a replica of the Holy Sepulchre in Jerusalem and belonged to the Knights Templar.

Gothic House Gothic house from the end of the 15th century, which is notable for the enormous pointed doorway with a moulded ring and large voussoirs, on the keystone of which a quartered coat of arms is engraved, on the first and fourth floors, three bands with wolves inscribed on them, and on the second and third floors, panels. On the second floor, there are three pairs of twinned windows, with semicircular arches, with second lobed arches with balls and ogees. The wooden eaves that crown the building are notable.

Santa María de Eunate is a Romanesque church on the Aragonese branch of the Way of St. James in Navarre. The church was built at the end of the 12th century in the Romanesque style with Mozarabic influences. The octagonal design is a reference to the Templars. There used to be a hospice here that belonged to the Order of St. John and today it is a hostel for pilgrims.

The Iglesia del Crucifijo in Puente la Reina is a fascinating historical monument deeply rooted in the history of the Camino de Santiago. Originally built in the 12th century by the Knights Templar, the church was later taken over by the Order of St. John of Jerusalem. The church consists of two different naves: a Romanesque one from the 12th century and a Gothic one that was added later. What makes this church really special is the impressive Gothic crucifix in the shape of a “Y”, one of the most remarkable Gothic sculptures in Spain.
