The Colegial de Santa Maria is the main church in the small town of Daroca. This collegiate church was built in the Romanesque period to house the Holy Altar Cloths. In 1239, during an attack by Moors, the priest hid consecrated hosts between altar cloths. Afterwards the cloths were found to have blood stain marks. The shrine holding these cloths is in the 15th Century Chapel of the Holy Relics. Also of interest is the 15th Century altarpiece and Gothic tombs.
