Estimated journey times
The old centre grew from three boroughs—Navarrería, San Cernin and San Nicolás—joined under the Privilege of Union in 1423. Santa María la Real Cathedral is a Gothic building of the 14th and 15th centuries; its cloister and the tomb of Charles III of Navarre are notable details.
The Citadel, begun in 1571, is a five-pointed Renaissance fort whose surviving bastions now border public green space. Sections of the medieval walls remain around the old quarter, where the Camino de Santiago enters through historic streets.
