 In 2006, Bernabé Cabañero Subiza, C. Lasa Gracia and J. L. Mateo Lázaro postulated that "the nerves of the vault [...] should have the section of horseshoe arches forming an eight-pointed star pattern with a dome agglomerated in the center, as those existing in the two domes of the transept of the Mosque of Córdoba.Completing the tour of the 11th-century palace, one arrives at the south portico, which consists of an arcade on its southern flank that gives access to a portico with two lateral stays.This portico was the vestibule of a great south hall that would have the same tripartite disposition of the existent one in the north side, and of which only the arcades of access of mixtilineal arches of geometric decoration remains.
