Hiniestra Curiosity · Barrios de Colina, Montes de Oca, Burgos A tiny settlement of eight inhabitants, a minor local entity of Barrios de Colina in the Montes de Oca district, 23 km from Burgos. It belonged to the Hermandad de Montes de Oca and the district of Juarros, and in the 1842 census it had ten households and twenty-six residents; by the mid-19th century it had twelve houses and appears described in the Diccionario de Pascual Madoz. Its church, under the invocation of the Natividad de Nuestra Señora and dependent on the archpriesthood of San Juan de Ortega, has been in ruins since the 1970s due to the archbishopric's neglect. Every 2 June it takes part with its banner in the pilgrimage of San Juan de Ortega, which brings together 26 villages, and celebrates its patronal feast on 12 October in honour of the Virgin.
