The Cathedral of the Immaculate Conception (), commonly referred to as the New Cathedral of Cuenca (), is the cathedral church in Cuenca, Ecuador. It is situated in front of Parque Calderon. The plan of the Cathedral was drawn up by Juan Bautista Stiehle (1829-1899) — a German-born friar who arrived in Cuenca from Alsace in 1873 — on suggestions made by Bishop León Garrido. The Cathedral took over the function of the nearby Old Cathedral that had become too small. Construction works started in 1885 and lasted for almost a century. This building combines many architecture styles, but Romanesque Revival is predominant. The cathedral is surmounted by three giant domes covered by striking blue and white glazed tile from Czechoslovakia. Its stained glass windows were created by Spanish artist Guillermo Larrazábal. Its towers are truncated due to a calculation error of the architect. If they had been raised to their planned height, the foundation of this Church to the Immaculate Conception, would not have been able to bear the weight. In spite of the architect's immense mistake, the skyline of its domes has become a symbol for the city. Its facade is made of alabaster and local marble, while the floor is covered with pink marble, brought from Carrara (Italy). When the Cathedral was first constructed 9,000 out of Cuenca's 10,000 inhabitants could fit in the building. History Church "El Sagrario" or Old Cathedral This Church is an antecedent for the later construction of the Cathedral of the Immaculate Conception of Cuenca. The Colonel Gil Ramírez Dávalos founded the city of Santa Ana de los Ríos de Cuenca on April 12, 1557 under the orders of Viceroy Andrés Hurtado de Mendoza. In the year 1565 the final location of this church is decided, in which today it is the Historical Center of the city. The development of this project was promoted with the financial support of the Viceroy. The materials used in its construction are simple and easily accessible, such as: stones and sand bordering the city, wood, brick and the warmth of the first ovens of the Spanish Crown. The cathedral counted on several transformations and remissions through time; in 1935 the last work was done on the tower and on the front facade. The erection of the bishopric of Cuenca was consolidated on April 2, 1786. In the year 1779, the Royal Certificate was issued by Carlos
