The Metropolitan Cathedral, dedicated to the Assumption of the Most Blessed Virgin Mary, occupies the north end of the Zócalo. The site originally was part of the Aztec Sacred Precinct (called the Teocalli) and contained the main tzompantli, or rack for the skulls of sacrifice victims. The first church was erected between 1524 or 1526 and 1532 and was elevated to the rank of cathedral on 2 September 1530 by Pope Clement VII. The foundations for a new cathedral were begun in 1562 and the foundation stone was laid in 1573 in the time of Archbishop Pedro Moya de Contreras and of the 4th Viceroy. Although the works had not been concluded, the cathedral received its first dedication on 2 February 1656. The completion in 1813 of the neo-classical additions designed by Manuel Tolsa was celebrated on 15 August 2013 by Cardinal Carrera who opened and entered through the Holy Door in the center of the façade prior to celebrating Pontifical High Mass in the cathedral.
