Church of the Blessed Virgin Mary

The Church of Santa Maria de Siones is located in the Valley of Mena, part of the comarca of Las Merindades in the Province of Burgos, Spain. The oldest reference to this church dates from 1001. The church was declared a Monumento nacional in 1931, and it is one of the most important and best preserved Romanesque churches of the Valley of Mena, despite the 19th-century restorations that altered its original scheme and replaced some of its sculptures with new statuary.
