This building has its origins dating back to the time of Hernán Cortés, who in 1523 ordered its construction on the ruins of Moctezuma Xocoyotzin's palace. It was known as the "Casas Nuevas de Moctezuma." Between 1560 and 1561, a request was made to the King for a Royal House to serve as the seat of the viceroyalty government. The first to occupy this building was the second viceroy, Luis de Velasco, with adaptations by architect Claudio de Arciniega. After Mexican Independence, the building was named the National Palace, becoming the seat of the executive, legislative, and judicial branches of government. It has undergone various remodels and repairs due to damage over time.
