Casa del Rey (Spanish for 'house of the king') is a historic building and former cabildo located in the historic center of Dorado, Puerto Rico.

The building, the oldest in town, provided housing for Spanish government personnel and also served as the regional military headquarters.

In converting it into a residence, López added two wings which created a U-shaped configuration around an interior patio.

In 1871, Casa del Rey became the home of Manuel Alonso y Pacheco, Puerto Rico's notable romantic writer.

[1][2] The house was restored by the Institute of Puerto Rican Culture in 1978[3] and is now a local history museum.
