What is the history of Castillo San Felipe Del Morro?

Christopher Columbus “discovered” and claimed for the Spanish Crown the Island of Boriken on November 16, 1493.

He named the island San Juan Bautista in honor of John The Baptist.

In 1508 Juan Ponce de Leon (Christopher Columbus’s lieutenant) founded the city of Caparra to serve as San Juan’s Island center of government.

The Spanish started construction of El Morro in 1539 and finished it in 1790.

One year later, Ponce de Leon moved the settlement to an islet on the island’s northeast shore (now Old San Juan) and named the city Puerto Rico (Rich Port).

Around 1522 the names were interchanged. They renamed the Island Puerto Rico and the capital San Juan.

Between 1533 and 1540, the Spanish built La Fortaleza, the first fortification in the San Juan harbor. Now, La Fortaleza is the oldest Governor’s Mansion in the Americas. 

Because of Puerto Rico’s privileged position, the world powers started calling the island “The Gateway to The New World.”

Puerto Rico was located very strategically for countries looking to colonize the Caribbean.

They said that whoever controlled the island of Puerto Rico would control the ocean routes from the Americas to Europe. Thus, the Spanish Crown knew they needed to defend Puerto Rico to keep their control of “The New World.”

The Spanish started construction of El Morro in 1539 and finished it in 1790. During those 250 years, El Morro expanded from a cannon mounted on a promontory to a six-level fortress.

El Morro defended Puerto Rico from several historical attacks. Here is a review of the most critical attacks Castillo San Felipe Del Morro faced.

In 1595 the famous English Privateer Sir Frances Drake was defeated when he attacked El Morro with 27 vessels and more than 2,500 men. 

But the English did not give up; in 1598, George Clifford, The Earl Of Cumberland, attacked San Juan.

Clifford learned from Drake’s mistake and took a different approach. 

The Earl of Cumberland disembarked outside the walls of El Morro, attacked by land, and succeeded. 

Puerto Rico was now under English control.

That British control lasted a short time; it only lasted almost two months.

Dysentery killed most English troops, and the ones who survived abandoned the island.

In 1625 The Dutch fought for their independence from Spain.

The Netherlands took the fight to the new world and attacked San Juan.

After 21 days of siege and battles, The Dutch started to run out of ammunition and supplies.

Unable to make The Spanish surrender El Morro The Dutch left, but as a “parting gift,” they burned down the city of San Juan.

In the middle of the eighteenth century, the Spanish Crown commissioned two Irishmen, Field Marshall Alexander O’Reilly, and Chief Engineer Colonel Thomas O’Daly, to reform the fortifications of Puerto Rico, including Castillo San Felipe Del Morro.

O’ Daly did the last major construction and renovation of El Morro just in time to defend Puerto Rico from the 1797 attack of The British.

On April 17, 1797, General Sir Ralph Abercromby came to San Juan with a 68-vessel fleet and 7,000 men to take over Puerto Rico.

The Spanish defeated Abrecombrie and protected the island.

One Hundred years later, in the Spanish-American war, the once unconquerable six-level fortress fell to the more sophisticated war technology of the United States.

A defeated, covered in smoke Castillo San Felipe del Moro was testimony that history had changed.
