Entrance to Callisto San Felipe del Morro

Puerto Rico history is marked by astonishing achievements and the determination of its people, no matter how long the odds might have seemed. The island’s historical monuments, structures, and artifacts speak to this, and when you experience these sites, you’re experiencing Puerto Rico’s political, economic, and cultural past enshrined in brick and stone.

From your starting point at the majestic Caribe Hilton in San Juan, you can visit plenty of historical sites around the island in just a few days’ time. To add texture and depth to your island vacation, here’s where to begin an exploration of Puerto Rico history.

Castillo San Felipe del Morro

In Old San Juan, standing like a timeless sentinel on a hill perched over the Caribbean, you’ll find Puerto Rico’s most famous historic landmark: Callisto San Felipe del Morro. This massive stone fortress was installed by Spanish colonizers to protect the island from invasion by sea. Construction began in the 16th century, and most of the work at what is commonly known today as “El Morro” was completed by 1790–though upgrades were added in the 19th and 20th centuries.

El Morro is a testament to the fierce determination of European settlers in Puerto Rico to protect the claims on their New World settlements. The fortress is now listed as a UNESCO World Heritage Site, and it’s open for exploration both inside and out.

La Fortaleza

Built between 1533 and 1540 on a cliff above San Juan Harbor, La Fortaleza (The Fortress) is located just over a half mile south of Castillo San Felipe del Morro. Like that fortification, it originally functioned as a defensive outpost to protect against ocean invaders. Since 1544, it’s been used as the governor’s mansion, which makes it (fun fact!) the oldest continually occupied executive residence in the Western Hemisphere.
Thirty-minute walking tours of the interior and exterior grounds at La Fortaleza are available each weekday between 8:15am and 3:30pm. When you need to refuel, there are tons of excellent restaurants in this part of the city.

Castillo San Cristóbal

In response to the continuing threat of invasion, Spanish colonial authorities constructed yet another formidable fortress just under a mile east of La Fortaleza. Work on Castillo San Cristóbal began in 1634 and was finally finished in the late 1700s, resulting in a 27-acre behemoth that stands as the largest Spanish fortification built anywhere in the New World.

Castillo San Cristóbal features three distinct levels, and you can explore its interior by traversing a series of tunnels that weave in and out of the complex. The fortress has been carefully preserved and restored, and its extensive outer grounds are popular with kite flyers and picnickers.
Like the capital city’s other grand fortifications, Castillo San Cristóbal has been designated a World Heritage Site by UNESCO. You can visit all three of them (Castillo San Felipe del Morro, Castillo San Cristóbal, and La Fortaleza) in a single day on foot as you explore Old San Juan.

Museo Castillo Serrallès

Museo Castillo Serrallès

Constructed on a hill overlooking the city of Ponce by a family of wealthy rum barons in the 1930s, the awe-inspiring Castillo Serrallès (Serrallès Castle) has been converted into a museum and architectural showplace that is open year-round to visitors.

Designed by local architect Pedro Adolfo de Castro y Besosa, the former home of the Serrallès family exemplifies the Spanish Revival style popular in the early 20th century. The mansion features spacious, luxurious rooms and receiving areas, carefully landscaped grounds with sprawling green lawns, and immense terraced gardens. While a tour of the property itself will likely be the highlight of your visit, you’ll also pick up fascinating details about the history of Puerto Rican sugarcane production and rum distillation from the museum.

El Museo Castillo Serrallès is in Ponce, on the island’s southern coast. From San Juan, take Highway 52 and you’ll reach your destination in under two hours.

Hacienda La Esperanza
The sugarcane industry was dominant in Puerto Rico for more than four centuries. With a visit to Hacienda La Esperanza in Manatí, you can take a step back in time to immerse yourself in a bygone era—one with effects that can still be felt today.

This 2,000-acre estate was a fully functioning sugar plantation in the 19th century. The hacienda (plantation house) and surrounding structures have been faithfully restored to give visitors an idea of how sugarcane was grown, harvested, and processed. Slave labor was used on plantations such as this well into the 19th century, and this history forms an integral part of the story that’s told at the site.

Hacienda La Esperanza has since transformed into the largest nature reserve in Northern Puerto Rico–home to mangrove forests, wetlands, estuaries, and native wildlife. The hacienda serves as a visitors center and museum. Find it about 36 miles west of San Juan, a drive that takes less than an hour via Highway 2 or 22.

Caribe Hilton

Yes, the Caribe Hilton itself has played an important role in the development of San Juan and more recent Puerto Rico history.

December 9, 2019 marks the 70th anniversary of the opening of the Caribe Hilton in San Juan, a property that stands as the crown jewel of Hilton’s investment in the Caribbean. This was the first Hilton hotel to open outside of the continental United States, and as such it’s made an indelible mark on the history of tourism in Puerto Rico.

Not only that, but this is the birthplace of the piña colada! The first version of what we today recognize as the famous tropical cocktail was poured right here in 1954. The piña colada went on to be recognized as the official drink of the island, so what better place to enjoy a true taste of Puerto Rico history?
