The Zugarramurdi Witches' Museum opened in July 2007 and aims to be a place where historical memory is preserved and where visitors can learn about the daily lives of those people.
The museum is located in the monastery, as the history of Urdax is closely tied to it. The Monastery of San Salvador is the only one founded by the Premonstratensian Order in the Kingdom of Navarre.
The Amaiur Archaeological Center–Museum, which opened in 2020, features a permanent exhibition on the castle and the archaeological remains discovered there by Aranzadi Zientzia Elkartea.
