22 Best Sights in Old San Juan, San Juan

This huge stone fortress, built between 1634 and 1783, guarded the city from land attacks from the east. The largest Spanish fortification in the New World, San Cristóbal was known in the 17th and 18th centuries as “the Gibraltar of the West Indies.” Five freestanding structures divided by dry moats are connected by tunnels. You're free to explore the gun turrets (with cannon in situ), officers' quarters, re-created 18th-century barracks, and gloomy passageways. Along with El Morro, San Cristóbal is a National Historic Site administered by the U.S. National Park Service; it's a UNESCO World Heritage Site as well. Rangers conduct tours in Spanish and English.

At the northwestern tip of Old San Juan, El Morro (the promontory) was built by the Spaniards between 1539 and 1790. Rising 140 feet above the sea, the massive six-level fortress was built to protect the port and has a commanding view of the harbor. It is a labyrinth of cannon batteries, ramps, barracks, turrets, towers, and tunnels, through which you're free to wander. The cannon emplacement walls and the dank secret passageways are a wonder of engineering. A small but enlightening museum displays ancient Spanish guns and other armaments, military uniforms, and blueprints for Spanish forts in the Americas, although Castillo San Cristóbal has more extensive and impressive exhibits. There's also a gift shop. The fort is a National Historic Site administered by the U.S. National Park Service, and a UNESCO World Heritage Site as well. Various tours and a video are available in English.

According to legend, in 1753 a young horseman named Baltazar Montañez got carried away during festivities in honor of San Juan Bautista (St. John the Baptist), raced down Calle Cristo, and plunged over its steep precipice. Historical records maintain the man died, but legend contends that he lived. (Another version of the story has it that the horse miraculously stopped before plunging over the cliff.) Regardless, this chapel was built partly to prevent further calamities. Inside is a small silver altar dedicated to the Christ of Miracles. Above the altar hang two religious paintings by Puerto Rico's famous painter José Campeche. You can peer in through the wrought-iron gates, which are usually closed.

San Juan's city hall was built between 1602 and 1789. In 1841, extensive alterations made it resemble Madrid's city hall, with arcades, towers, balconies, and an inner courtyard. Renovations have refreshed the facade and some interior rooms, but the architecture remains true to its colonial style. Only the patios are open to public viewings. A municipal tourist information center and an art gallery with rotating exhibits are in the lobby. Call ahead to schedule a free tour.

The original structure here was a wooden house built in 1521 as a home for Ponce de León; he died in Cuba without ever living here. His descendants occupied the house's sturdier replacement, a lovely colonial mansion with tile floors and beamed ceilings, for more than 250 years. It was the home of the U.S. Army commander in Puerto Rico from the end of the Spanish-American War in 1898 to 1966. Several rooms decorated with colonial-era furnishings are open to the public. The lush garden, complete with watchtower, is a quiet place to unwind.

The restored home of 18th-century naval hero Don Ramón Power y Giralt is now the headquarters of the Conservation Trust of Puerto Rico and its nonprofit, Para La Naturaleza. On-site are several displays highlighting the physical, cultural, and historical importance of land and properties on the island under the trust's aegis. The goal of the trust is to increase the amount of protected lands in Puerto Rico from (currently) 8% to 33% by the year 2033. Displays are in Spanish, but there are note cards in English for the changing exhibitions. A gift shop sells toys, Puerto Rican candies, and eco-friendly souvenirs.

The Catholic shrine of Puerto Rico had humble beginnings in the early 1520s as a thatch-roofed wooden structure. After a hurricane destroyed the church, it was rebuilt in 1540, when it was given a graceful circular staircase and vaulted Gothic ceilings. Most of the work on the present cathedral, however, was done in the 19th century. The remains of Ponce de León are behind a marble tomb in the wall near the transept, on the north side. The trompe-l'oeil work on the inside of the dome is breathtaking. It is the oldest cathedral in the United States.

One of Old San Juan's best-kept secrets, this remarkable cemetery provides a peaceful respite from the bustle of the city. Sandwiched between El Morro and La Perla, it offers a panoramic view of the Atlantic Ocean and an enviable resting place for the many notable figures fortunate enough to be buried here. Dating from the early 1800s, the cemetery was originally administered by Carmelite nuns. Today you can stop by the ornate tombs (many of which are topped with graceful marble sculptures) to pay your respects to an illustrious group of Puerto Rican political figures, intellectuals, artists, and revolutionaries, including José Celso Barbosa, José Ferrer, Pedro Albizu Campos, Rafael Hernández, and Ricardo Alegría.

This tiny but fascinating museum honors Felisa Rincón de Gautier, who served as San Juan's mayor from 1946 to 1968. Throughout her life, "Doña Felisa" worked tirelessly on various public causes, including women's voting rights and health care for the poor. Her preschools, known as Escuelas Maternas, were used as the model for the United States' Head Start program. Extremely well connected politically, both on the island and abroad, she was an egalitarian figure who rose to power at a time when women and politics were not mentioned in the same breath. Even if you have no interest in her story, stop by for a peek inside one of Old San Juan's historic houses. Guided tours in English or Spanish are available.

This nonprofit foundation serves many functions: museum; performance space; dance and music school; and archive preserving Puerto Rican contributions to music, dance, television, theater, film, and other aspects of culture. In a 300-year-old building once used by the Spanish as a meteorological lookout, you can view rotating exhibitions, hear live Latin music in the evenings, or take a bomba or plena dance class. A small store sells music by Puerto Ricans in every genre, from classical to salsa. Signed posters from El Gran Combo, Tito Puente, and Willie Colón—as well as Ricky Martin's platinum record—line the walls. Check the website or call ahead for the performance schedule.

With its vaulted ceilings, this little church is a splendid example of 16th-century Spanish Gothic architecture. It was built under the supervision of Dominican friars in 1532, making it the second-oldest church in the western hemisphere. The body of Ponce de León, the Spanish explorer who came to the New World seeking the Fountain of Youth, was buried here for almost three centuries before being moved to the Catedral de San Juan Bautista in 1909.

Sitting atop the fortified city walls overlooking the harbor, La Fortaleza was built between 1533 and 1540 as a fortress, but it proved insufficient, mainly because it was built inside the bay. It was attacked numerous times and occupied twice, by the British in 1598 and the Dutch in 1625. When the city's other fortifications were finished, this became the governor's palace. Changes made over the past four centuries have resulted in the current eclectic yet eye-pleasing collection of marble and mahogany, medieval towers, and stained-glass galleries. It is still the official residence of the island's governor, making it the Western Hemisphere's oldest executive mansion in continuous use. Guided tours of the gardens and exterior are conducted several times a day in English and Spanish; call ahead, as the schedule changes daily. Proper attire is required: no sleeveless shirts or very short shorts. Tours begin near the main gate in a yellow building called the Real Audiencia, housing the Oficina Estatal de Conservación Histórica (State Historic Preservation Office).

Deemed Puerto Rico’s most famous “slum” or “shantytown,” La Perla has a checkered past and visitors have long been advised to avoid it altogether because of drug activity. In 2011, a raid by the Drug Enforcement Agency removed many of those responsible from the neighborhood. Then in 2017, Luis Fonsi released the global hit Despacito, filmed in La Perla. Since then, tourists have been visiting more frequently, undeterred by warnings. The neighborhood is in a point of transition, and like other parts of the island has used street art to revitalize the architecture and engage residents. Stop by El Malecon to see murals and grab a tripleta from La Cantina on the way. If you are planning to visit, do not take pictures without permission and avoid carrying any valuables. To exercise increased caution, go with a walking tour or local guide and avoid visiting at night.

On the second floor of the imposing former military barracks, Cuartel de Ballajá, this museum houses four permanent exhibits covering folk art, African and Native American heritage, and colonization. You'll also find temporary exhibitions of works by regional and international artists. A wide range of handicrafts is available in the gift shop. Before visiting, it's best to check the website for current hours.

A bustling marketplace in 1857, this handsome building now houses the small San Juan Museum. You'll find rotating exhibits of Puerto Rican art, plus tableaux and audiovisual shows that present the island's history. Concerts and other cultural events take place in the huge interior courtyard.

Dedicated to the artistry of the printed word, this museum counts among its holdings approximately 400 books printed before the 15th century—one of the larger such collections in the western hemisphere. It also owns two royal decrees from King Ferdinand and Queen Isabella that date from 1493, the year Columbus first reached Puerto Rico. Because the museum is in a temporary location while long-term restorations to the permanent building are underway, only a small portion of the 6,000-piece collection is on display. Highlights include a page from the Gutenberg Bible and a 12th-century lunar-cycle calendar. The gift shop has a terrific collection of posters that draws customers from all over the world.

Built in the mid-19th century to honor the Spanish princess of Asturias, this street has a broad pedestrian walkway and is spruced up with flowers, trees, benches, and streetlamps. Unfurling westward from Plaza del Inmigrante along the base of the fortified city walls, it leads to the Fuente Raíces, a striking fountain depicting the various ethnic groups of Puerto Rico. Take a seat, and watch boats zip across the water. Beyond the fountain is the beginning of Paseo del Morro, a well-paved shoreline path that hugs Old San Juan's walls, leading past the city gate at Calle San Juan and continuing to the tip of the headland, beneath El Morro.

A statue of Christopher Columbus stands atop a soaring column and fountain in this bustling Old San Juan square, catercorner to Castillo San Cristóbal. Once called St. James Square, it was renamed in 1893 to honor the 400th anniversary of Columbus's arrival in Puerto Rico; bronze plaques on the statue's base relate episodes in his life. Local artisans often line the plaza, so it's a good place to hunt for souvenirs. Cool off with a fresh fruit frappé or smoothie at the kiosk.

The Old City's original main square was once used as military drilling grounds. Bordered by Calles San Francisco, Rafael Cordero, San José, and Cruz, it has a fountain with 19th-century statues representing the four seasons as well as a bandstand, a small café, and a kiosk selling snacks and fruit frappés. The Alcaldía commands the north side. This is a popular, bustling meeting place, often filled with artists sketching caricatures, pedestrians in line at the food stands, and hundreds of pigeons waiting for handouts.

According to legend, the British, while laying siege to the city in 1797, mistook the flaming torches of a rogativa (religious procession) for Spanish reinforcements and beat a hasty retreat. In this little plaza, a monument of a bishop and three women commemorates the legend. The striking contemporary statue was created in 1971 by the artist Lindsay Daen to mark the Old City's 450th anniversary. The fine view of La Fortaleza and the harbor is a bonus.

Dating from 1520, this was one of the five original entrances to the city and is the only one still in its original state. The massive gate, painted a brilliant shade of red, gave access from the port and welcomed diplomats into the city. It resembles a tunnel because it passes through La Muralla, the 20-foot-thick city walls.
