Almost every significant Spanish city has a magnificent cathedral, and Pamplona makes no exception. The Gothic style temple is located in the oldest part of the town known as Pompaelo in the Roman age. The cathedral was built in the 15th century, but the facade and towers were added in the late 18th century to bring more Neoclassical outlook to the building.

The temple is dazzling from the outside and nonetheless breathtaking from the inside. The tomb of King Charles III of Navarre and his spouse is set in front of the choir. The Diocesan Museum and the Lignum Crucis (believed to be a fragment of the real Holy Cross) are among the objects that can be seen too.
