The Museo Nacional de las Culturas (MNC; National Museum of Cultures) is a national museum in Mexico City dedicated to education about the world's cultures, both past and present. It is housed in a colonial-era building that used to be the mint for making coins. Prior to this, the site was the home of the location of the Moctezuma's Black House. The mint was moved to Apartado Street in 1850, and the building was used for various purposes until it was converted to its current use in 1966. Aztec site The museum is located on the site of the original Aztec building that was a part of Moctezuma's "New Palaces" complex called the "Casa Denegrida" (Black House) by Spanish conquerors, who described it as a windowless room painted in black. In here, Moctezuma would meditate on what he was told by professional seers and shamans. During the Conquest, this Black House, along with the rest of Moctezuma's New Palaces was nearly destroyed. This site was part of lands given to Hernán Cortés by the Spanish Crown as a reward for the conquest of Mexico, and Cortés rebuilt the New Palaces/Black House complex in Spanish style, using much of the building materials of the old Aztec buildings. Cortes’ son later inherited this palace, only to later sell it back to Felipe V in order to establish the vice-regal palace. Recently, excavations here and next door at the National Palace have unearthed parts of a wall and a basalt floor believed to be part of the Black House. More excavations are planned. Colonial era mint Originally, minting operations were based in the city hall. However, due to the increased prosperity of the colony and the need for more coin production, minting operations were moved here in 1731. The mint's director at the time, Nicolás Peinado, was also an architect and made the initial plans. Worked was carried out by Pedro de Arrieta and Lorenzo Rodríguez. However, problems with the remodeling surfaced, resulting in the viceroy naming Jose Eduardo de Herrera to take over, and Peinado ended up in jail. The remodeling was finally completed by Luis Diez Navarro. This mint is responsible for the name of the street on which it is located, called Moneda, which means "coin". The building was again expanded between 1772 and 1779 by Miguel Constanzó, Lorenzo Rodriguez, and Jose Damian Ortiz de Castro. Conversion to museum In
