The donation of the commandery of Wamba Historical milestone · Arroyo de la Encomienda, Campiña del Pisuerga, Valladolid Image of Arroyo de la Encomienda, not of the place itself. The Encomienda of Wamba was a commandery of the Order of the Hospital of Saint John of Jerusalem, based at the Mozarabic monastery of Santa María de Wamba (Valladolid), in the Montes Torozos district. The infanta Sancha Raimúndez, sister of King Alfonso VII, donated the monastery and its possessions to the Hospitallers on 10 June 1140, giving rise to one of the leading Hospitaller commanderies north of the Sistema Central mountains. At its greatest extent, the lordship comprised, besides Wamba, the Valladolid possessions of Arroyo de la Encomienda, Castrodeza, Adalia and, until the 14th century, San Miguel del Pino; it was from this holding that the present-day municipality of Arroyo de la Encomienda took its name, which it kept until Mendizábal's disentailment, in 1836, extinguished it and transferred its assets to the State. 1140 Photo: Pedro M.
