Palace of the Kings of Navarre

The Palace of the Kings of Navarre is a medieval stone structure featuring stone walls and six rib vaults that create its distinctive interior spaces. Below ground lies a Romanesque crypt with six flared windows, plus a deep underground chamber once used for winter storage.

The building was first erected in the 12th century to serve as a royal residence for Navarrese monarchs. When the kingdom lost independence in 1512, it transitioned to a viceregal role under Spanish authority.

The building served as the administrative center where the kingdom's affairs were managed and recorded. Today it reflects how Navarre organized its government and kept records of its independence and later development.

The building is located within the old city walls and remains visible as you walk through the historic streets. Hours may vary during festival periods, so it is worth checking locally if you plan to visit during those times.

Beneath the building lies a remarkable medieval ice storage chamber that extends about seven meters below ground level. Snow was stacked in layers with straw to preserve food and medicinal materials long before modern refrigeration existed.
