It is a Catholic temple whose 18th century ex-vows in the chapel made Saramago go to Sabugal in his Journey to Portugal, but he returned discouraged not to have seen them. The ex-vows of Our Lady of Grace are now properly restored and exposed in the chapel of the sanctuary for those who want to see these authentic masterpieces of sacred art and some of them dedicated to Our Lady of Grace, in which the miracle she granted a nun, affected with cancer in a breast, but who was saved by divine intervention, is thanked.
