Quick Takeaway

‍

A Brief Overview of the Two Forts

Old San Juan is home to two of the most important Spanish fortifications in the Americas: Castillo San Felipe del Morro (El Morro) and Castillo San Cristóbal.

They sit only a short walk apart, but each served a distinct purpose:

• El Morro protected the bay and incoming ships
  
• San Cristóbal protected the city from land attacks
  

Together, they formed the most formidable defensive system in the Caribbean.

El Morro: Puerto Rico’s Most Iconic Fortress

Why Visit El Morro

El Morro is the older and more recognizable of the two forts — a symbol of Puerto Rico itself.

El Morro Highlights

• Older by more than a century (construction began in the 1530s)

• Sweeping ocean views and dramatic cliffside design
  
• Key role in the Dutch Attack of 1625
