The Museo de las Casas Reales (English: Museum of the Royal Houses) is one of the important cultural monuments built during the colonial era in Hispaniola, now the Dominican Republic.

[2] The building dates back to the sixteenth century, and was built to house the administrative offices of the Spanish colonies in the Americas, at the time any trespassers would be sentenced to death.

The palace was built by orders of the Spanish Crown, represented by King Ferdinand II of Aragon, on October 5 of 1511 to house the main government offices of the colony in two interconnected buildings (hence the plural Casas Reales).

The building was later restored to its original 16th-century appearance and was established on October 18, 1973, during the administration of President Joaquín Balaguer,[3] as a museum to highlight the history, life and customs of the inhabitants of the Spanish colony.

A self-guided tour giving a sequential history of the island includes a portable audio speaker that is available in various languages.
