The influence of the Pilgrim's Way and the Jewish Quarter -the third most important in Navarre after those of Tudela and Pamplona- permeates the whole city. It was established in 1090 by King Sancho Ramírez and enjoyed its golden age in the 12th and 13th centuries. From this time dates the palace of the Kings of Navarre, one of the few non-religious architectural relics of its era that survives in Spain, and which houses the Gustavo de Maeztu Museum. The façade is framed at each end by two columns superimposed with four beautiful capitals, two featuring plants and two narrative ones. 

The lower capital of the left-hand column is the most famous of the two narrative capitals, in which you can clearly distinguish the battle between Roland and Farragut, the former being Charlemagne's foremost knight and the latter a giant Moor The palace is located in the Plaza San Martín, where you can drink from the 16th-century water fountain before continuing your visit.

Amongst the religious buildings, a visit to the ruins of the medieval Church of San Pedro de Lizarra is a must: see the Roman stone pillar resting against the south wall. The Church of San Pedro de la Rúa (the largest church in the city whose 12th-century cloister is considered to be one of the most valuable in terms of Romanesque sculptural richness in Navarre), of late Romanesque style, has a 13th century façade and a 12th-century cloister.

- The Church of San Miguel:  It is a building as simple as it is beautiful; its interior houses some valuable artistic treasures. The construction of San Miguel, which stands on the top of a rocky escarpment known as "La Mota", began at the end of the 12th century, but work continued over the years, which allows us to identify the different styles of the building. 

Its northern doorway, one of the most representative examples of late Romanesque, and the Gothic altarpiece of Santa Elena inside the church, are worthy of special attention. The external appearance of the building is impressive, affording contrasting volumes such as the Baroque tower at the top of the building and the stone mass of the medieval tower at the foot of the nave. 

But the real artistic treasure is the North façade, representative of late Hispanic Romanesque, which is reached by ascending a long staircase

- The Church of Santo Sepulcro:  Now it is the visitor's imagination that plunges into the Middle Ages to reconstruct the building, whose surprising façade is one of the finest examples of Gothic sculpture in Navarre. Dedicated sculptors worked on it delicately to create the apostles and relate scenes from the life of Jesus in an original way. 

Building work on the church started in the 12th century. It was interrupted in the 14th century, so the ambitious initial project of a three-nave church similar to San Pedro de la Rúa, San Juan or San Miguel (all constructed towards the end of the Romanesque period in Estella-Lizarra) was left unfinished.

The Church of the Holy Sepulchre contains a combination of architectural elements from different epochs. The apse of the nave of the Gospel is Romanesque, from the end of the 12th century. The construction of the headers and of part of the Epistle began in the 14th century, in the form of pentagon-shaped apses. The unfinished part of the work is particularly seen in the ground floor and the nave of the Epistle.
