The site of the cathedral is the oldest part of the
Roman Pompaelo. Archaeological excavations in 1994 have revealed streets and buildings from the 1st century BC. The oldest cathedral was demolished in 924 during the invasion of
Abd-al-Rahman III,
Caliph of Cordoba. During the reign of
Sancho III (1004–1035) the church was reconstructed. That church was demolished from 1083 to 1097, and the
Romanesque cathedral was built from 1100 to 1127. It collapsed in 1391, with only the façade remaining. The building of the current Gothic church began in 1394 and lasted to 1501. The floorplan is
cruciform with
ambulatory, a central
nave and four shorter aisles, all covered by partially polycromed
rib vault. The style is very influenced by
French models. The sculpture of the interior includes the
tomb of Charles III of Navarre and Eleanor of Castile, by (1419), and the image of Royal Saint Mary, a Romanesque
woodcarved silverplated sculpture. The
choir, with its
Renaissance choir stalls (1541), is separated from the nave by a Gothic iron grating (1517). There was a
Renaissance retable (1598) in the
presbytery, now in the church of Saint Michael in Pamplona. In the lateral chapels there are two
Gothic retables (, 1507); one Italian Renaissance retable (16th century); one late Renaissance
retable (1610, polycromed in 1617); and five
Baroque retables (1642, 1683, 1685). ==Cloister==
