Ermita Templaria de San Bartolomé, Cañón del Río Lobos Natural Park

The church of San Juan de Otero, now dedicated to San Bartolomé, is located inside the natural park of the Cañón del Río Lobos, actually in the non-municipal term called: Comunero de San Bartolomé, governed by the Soria municipalities of: Herrera de Soria, Nafría de Ucero and Ucero in Castilla y León; it was built in the first quarter of the 13th century, when the Romanesque style gave way to Gothic, a transition that was reflected in the architectural work. It was part of a Templar monastery of which only the chapel is preserved.
