The Casa Blanca, which translates to the White House, is the oldest residence and fortification in Old San Juan. Architects designed the house for Juan Ponce de León and his family, but the Spanish conquistador died before he could take up residency. Now, the home is a museum with 16th and 17th-century artifacts and an informative exhibit. A modest admission fee pays for a guided tour, revealing the secrets and surprises of this centuries-old home. The adjoining hidden gardens, a spectacular sight, are free to access. Come on a hot day to escape the sun and relax near the fountains.
