Irulegui castle is located on the Sierra de Aranguren in the municipality of Laquidáin.
During the Iron Age it there was a castro de los Vascones. This pre-Roman fort was destroyed around 76 BC. as a consequence of the rebellion.
Although there are legends that suggest the existence of the castle (or, at least, of a defensive structure in this place) during the Almanzor raids in the 11th century, the first reliable documents of the castle dates from the late 12th century.
In 1416 the castle was modernized, adding a triangular structure to the front. In 1494, the kings Catalina and Juan III (Juan de Labrit), agreed its destruction before the push of the Beaumonteses, who controlled the fortress, and consequently, the Pamplona Basin.

It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
