Sights include a citadel dating from the [[Al-Andalus]] period in the 9th century, a bridge of seventeen arches, and many remains of old walls. In 939 it was the scene of a  [[battle of Simancas|battle between]] the Christian troops under [[Ramiro II of León]] and the Moors of [[Abd-al-Rahman III]].

The citadel is now the [[Archivo General de Simancas]], sometimes called the Archivo General del Reino, to which the national archives of Spain were removed by order of [[Philip II of Spain|Philip II]] in 1563. Their transference thither was first suggested to [[Charles V, Holy Roman Emperor|Charles V]] by [[Francisco Jimenez de Cisneros|Cardinal Ximenes de Cisneros]]. The extensive alterations were made by three 16th century architects, [[Juan de Herrera]], [[Alonso Berruguete]] and [[Juan Gómez de Mora]]; the arrangement of the papers was entrusted to Diego de Ayala.

They occupy forty-six rooms, and are arranged in upwards of 80,000 bundles (33,000,000 documents), including important private as well as state papers. The [[Archivo General de Indias|archives of the Indies]] were transferred in 1784 to the Lonja of [[Seville]]. Permission to consult the documents at Simancas can be readily obtained.
