The Sanctuary of Our Lady of Oro is a place of worship in the Zuia Valley of northern Spain. It is about 3.5 kilometres (2.2 mi) from Murgia, in the center of the valley. The first known document mentioning it dates to 1138.
Local archeologists conducted four excavations from 1964 to 1967, and found evidence of human habitation in three eras. The oldest dates to the late Bronze Age (850-700 BC). A later community inhabited the area from 450 to 350 BC, followed by settlement during the later Roman Empire.
Nothing remains of the original Romanesque church. According to some historians, the sanctuary dates from the late 11th century to the 12th century. This is evidenced by its Romanesque images, similar to those in churches in the nearby villages of Domaikia, Markina-Xemein and Gillerna. The main church vaults were apparently constructed from the end of the 14th to the 15th century, with false plaster vaults in the sacristy dating to 1771.
The church's Baroque altar, built by Antonio de Alvarado in 1691, was preserved after the 1964 renovation and the medieval statue of Our Lady of Oro was restored in 1930. There are two chapels, one dating to 1638 and the other to 1761.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
