The Navarre Kings’ Palace stands in Plaza San Martin. It is Navarre’s last and only roman architecture exponent (late XII century). The building’s facades, with its two ashlar masonry bodies separated by a molding impost, give the Palace a unique character. The la Rúa façade has columns at each side. The same are built in a superposed way, and don’t match the height of the corresponding upper flats’ levels. The left column’s capital, shows the battle between Rolán and Ferragut, and is signed by Martines de Logroño. In its horizontal front Rolán breaks the giant down with a spear. In the other two, Ferragut attacks Rolán with a thorn ball and a thoroughbred horse. The skillfully carved figures have quite a long canon. The capital on the right is decorated with scroll wrapped leafs. Four powerful half point arches sitting on rectangular pillars, seem to pierce the first body. The second body has a series of openings in the wall: four windows divided into four small arches, slightly aimed with exterior archivolts. They are supported by three small columns, the one at the center being affixed to the wall. The ones at each end have finely crafted capitals, which could very well be compared in style to the neighboring cloister of San Pedro de la Rúa.
