Pamplona (Iruña or Iruñea in Basque) was the capital of the former Kingdoms of Pamplona and later Navarre, and is the capital of the autonomous community of Navarre today. Among other things, it is well known for the annual festival of San Fermín (the Sanfermines) held every year between the 6th and the 14th of July, which includes (but is not limited to) the famous running of the bulls.
The public albergues tend to be closed during the Sanfermines.
What to see in Pamplona/Iruña
Catedral de Pamplona
The Catedral Metropolitana de Santa María la Real used to be the coronation venue of the kings of Navarre. Some of them are also buried here, most notably Charles III of Navarre with his wife Eleanor of Castile.
Ciudadela de Pamplona
The Citadel was built in the 16th and 17th centuries to strengthen the defenses of Pamplona but also to keep the locals in check (Navarre had only been occupied by Castile and Aragon recently). Originally a five-pointed star, the two points looking towards the city were demolished at the turn of the 19th and 20th centuries to allow for residential expansion.
