In the heart of Old San Juan lies a remarkable historical monument — Casa Blanca. Built back in 1521, this elegant building served as the residence for the family of Puerto Rico's first governor, Juan Ponce de León. The site is recognized as one of the oldest surviving European structures in the Western Hemisphere.

Today, Casa Blanca carefully preserves its heritage as a house museum. Managed by the Institute of Culture, it recreates the authentic atmosphere of the colonial life of a wealthy Spanish family in the 16th and 17th centuries. Visitors can see rare artifacts, antique furniture, and tapestries that transport them to the Age of Discovery.
The building's architecture is impressive: a two-story stone house with an entrance adorned by majestic stone lions and the Ponce de León family crest. Throughout its long history, Casa Blanca has served as the island's first defensive fortification and a quiet family sanctuary, preserving the spirit of Old Spain to this day.
