The Holy Spring of Caballar Nature · Caballar, Comunidad de Ciudad y Tierra de Segovia, Segovia The Fuente Santa is the spring at Caballar where, according to tradition, San Valentín and Santa Engracia, siblings of San Frutos, patron saint of the diocese of Segovia, were martyred. It lies to the west of the town centre, next to the municipal dehesa, between the Mulas stream and the Carravillar path, and is the central point of the Camino de San Frutos, which links Segovia with the saint's ermita in the Hoces del Río Duratón. Around it is held the rogation of the Mojadas de Caballar, in which the relics of the saints are immersed in its waters at the request of the villages of the former vicariates of Turégano, Fuentepelayo, Pedraza and Trescasas; the oldest one documented dates from 1593. The present-day templete was built in the 18th century and the nearby ermita in the early 19th. Photo: Camino del Puerto (CC BY-SA 4.0) What to see and do in Caballar
