The Sagrario Church (Shrine Church) - also known as the Old Cathedral of Cuenca is a temple whose construction began in the mid-16th century, and was considered the main Spanish place of worship during the time of Spanish colonization in Cuenca (Ecuador). Today it functions as the Museum of Religious Art, known for its wide variety of altars and the history it offers. It is located in the center of the city of Cuenca, and one of its most emblematic museums, which is located in Parque Calderón, in front of the New Cathedral. It is part of the Historic Center, the same one that was named a World Heritage Site by UNESCO in 1999, making it one of the most emblematic places in Cuenca as it is the only church that has a bellows organ, which is It is located inside at the back of the building. It was used as a musical accompaniment to the choirs. However, it is now out of service. History Planning for the church started in 1557 and construction began ten years later, using stones for the foundation and walls from the ruins of Tomebamba. During the colonial period the church was the main center of worship for the "Parish of the Spaniards"; it was reserved for the people from Spain, while indigenous people had to stay outside or worship elsewhere. The organ was added in 1739, and the clock was set in the tower in 1751. In 1787 the bishopric was established in Cuenca, and the church became a cathedral. The new tower erected in 1868 carries a memorial plate: Torre más célebre que las pirámides de Egipto ("Tower more famous than the Egyptian pyramids") in reference to the use of the old tower as a key reference point for the French Geodesic Mission in 1736, which determined the arc of the meridian. In 1880 construction for the New Cathedral was begun. With the consecration of the New Cathedral, the Old Cathedral ceased to be used for regular services. After a restoration that started in 1999 the Old Cathedral serves today as the "Museum for Religious Art" and a venue for concerts and cultural events. Among others it displays sculptures by Miguel Velez and Gaspar Sangurima and paintings by Daniel Alvorado and Nicholas Vivar.
