The church of Nuestra Señora del Collado Monument · Valtajeros, Tierras Altas, Soria Image of Valtajeros, not of the place itself. The church of Our Lady of Collado, in Valtajeros, was built in the 12th century in a border enclave between Christians and Muslims and on the boundary with Navarre, which explains its fortress-like appearance: its walls are topped with battlements and arrow slits, and the east wall ends in a double-opening bell-gable. The doorway, on the south wall and hidden by a later porch, shows two plain archivolts over undecorated jambs. Its interior, with a single nave, is covered by a very pointed barrel vault divided into four bays, with a square apse unusual for the area. Declared a monument on 26 March 2007, it is the main building of a municipality of sixteen inhabitants, situated at 1,253 metres and one of the highest and most depopulated in the province.
