It is the former official residence of the governors of Havana, known as "Captain General". Located on the east side of Old Havana's "Plaza de Armas" and home to the Museum of the City of Havana or "Museo de la Ciudad", this palace houses rare and expensive artefacts and artefacts from the colonial era of Havana. The original decoration of the palace rooms has been preserved to reflect the same details of that era.
