26 historic landmarks in Puerto Rico to visit

Updated October 15, 2026. Dates and designations come from the National Park Service, UNESCO and the National Register of Historic Places and National Historic Landmark records (via Wikipedia’s articles on each site). Fees for the two San Juan forts are from the NPS. Hours change, so check each site before you go.

Puerto Rico’s landmarks span more than 700 years: Indigenous ball courts in the mountains, the oldest European forts and churches under the US flag, and 19th-century lighthouses on every coast. Below are 26 historic landmarks, grouped by region so you can plan them as day trips. Most visitors start in Old San Juan, where a dozen of them sit within walking distance of each other.

Old San Juan landmarks

1. Castillo San Felipe del Morro

Spain started El Morro in 1539 to command the mouth of San Juan Bay, and kept enlarging and repairing it for roughly 250 years. The US Army later used it as part of Fort Brooke, from 1898 to 1961. Today the National Park Service runs it as part of the San Juan National Historic Site, which is often described as the oldest European construction under US jurisdiction. Together with La Fortaleza, the forts and walls were named a UNESCO World Heritage Site in 1983. Plan your visit with our El Morro guide.

2. Castillo San Cristóbal

Where El Morro faces the sea, San Cristóbal was built to stop attacks by land. The NPS dates it from 1634 to 1790, with most of the work done after 1765, and at its fullest it spread over about 27 acres, which is why it’s called the largest fort Spain ever built in the Americas. Tickets: $10 for visitors 16 and older covers both forts for 24 hours, children under 16 get in free, America the Beautiful passes are valid and the park doesn’t take cash.

3. City walls and San Juan Gate

Work on the masonry walls began in 1634, the same year as San Cristóbal, and by 1783 they wrapped the whole old city. The NPS notes they are about 20 feet thick and once had four main gates. Only one survives: the Puerta de San Juan on the west side, once nicknamed the Water Gate because it opened onto the old harbor.

4. La Fortaleza

Raised between 1533 and 1540 as the city’s first fortress, La Fortaleza became the governor’s residence and has kept that role ever since; no governor’s home anywhere in the Americas has been lived in for longer. It shares the 1983 UNESCO listing with the forts.

5. Casa Blanca

Work began in 1521, right after the capital moved from Caparra to the islet, on a house meant for Juan Ponce de León and his family; the main building is dated 1523–1525. It also served as the islet’s first defensive post. The Institute of Puerto Rican Culture looks after it today.

6. Cathedral of San Juan Bautista

San Juan’s cathedral was founded in 1521; construction of the present building started in 1535 and wasn’t finished until 1802. It is counted among the oldest cathedrals in the Americas and holds the tomb of Juan Ponce de León, plus a national shrine dedicated to Our Lady of Divine Providence, Puerto Rico’s patron saint.

7. San José Church

Dominican friars founded this church in 1532 as part of their convent of Santo Tomás de Aquino. The convent was closed and secularized in 1836, but the church itself stayed open.

8. Capilla del Cristo

A small chapel built between about 1753 and 1780 at the far end of Calle del Cristo, a cobblestone pedestrian street. Every year from June 24, Saint John’s Day, to June 29, the street holds a festival that goes back to before the mid-1800s.

9. Cuartel de Ballajá

These huge barracks next to the El Morro lawn were built between 1854 and 1864 for regiments of Spanish and island soldiers, and they were the last large construction project of the Spanish Crown in the Americas. Owned by the Puerto Rico government since 1976, the building is now home to the Museo de las Américas and to the Academia Puertorriqueña de la Lengua Española, the island’s Spanish-language academy.

10. Teatro Tapia

Built in 1824 and named for the poet and playwright Alejandro Tapia y Rivera, this horseshoe-shaped, Italian-style theater with three tiers of boxes faces Plaza de Colón. For more than a century it was the center of the city’s cultural life, and the municipality still owns it.

11. Santa María Magdalena de Pazzis Cemetery

Begun in 1863 just outside El Morro’s walls, the cemetery runs along the Atlantic between the fort and La Perla, and many of Puerto Rico’s best-known figures are buried here. Details and etiquette are in our cemetery guide.

12. Paseo de la Princesa

This half-mile promenade was laid out from 1852 to 1854 in honor of the Spanish infanta Isabel. It hugs the southwest walls, passes the old La Princesa prison building and ends at the San Juan Gate, with lampposts, fountains, food and craft vendors along the way. More in our Paseo de la Princesa guide.

13. El Capitolio

Just outside the walls in Puerta de Tierra, Puerto Rico’s Capitol was built from 1921 to 1929 to plans by architect Rafael Carmoega and is clad in white marble. It is the seat of the Legislative Assembly, and the original documents of the island’s Constitution are on display under the dome. Tour details are in our Capitol guide.

14. Caparra ruins (Guaynabo)

Juan Ponce de León founded Caparra, the first Spanish settlement on the island, in late 1508. The settlers soon moved the capital to the San Juan islet and its better harbor, and the foundations left behind are now a National Historic Landmark.

Ponce, the south and San Germán

15. Tibes Indigenous Ceremonial Center (Ponce)

Archaeologists credit the plazas and ball courts here to the Igneri, a pre-Taíno people, with Taíno communities settling the area later. Tibes also holds the largest Indigenous burial ground found so far in the region, with 186 sets of human remains.

16. Ponce Cathedral (Nuestra Señora de Guadalupe)

The cathedral stands in the middle of Plaza Las Delicias. Its story starts with a small chapel built on the spot in 1670, which became a parish church in 1692; the current neoclassical church, with its two square towers, has been rebuilt after fires and earthquakes. The composer Juan Morel Campos played its pipe organ, and it was added to the US National Register in 1984.

17. Parque de Bombas (Ponce)

Ponce’s red-and-black firehouse dates to 1882 and sits on Plaza Las Delicias behind the cathedral. It worked as a fire station until 1990, its colors inspired the city flag, and it is now a museum. See our Parque de Bombas guide.

18. Castillo Serrallés (Ponce)

Built in 1930 on a hill above the city for Juan Eugenio Serrallés, son of the founder of the Serrallés rum distillery, this Spanish Colonial Revival mansion is now a museum about the island’s sugar and rum industries.

19. Hacienda Buena Vista (Ponce)

Founded in 1833, this farm grew fruit and corn before switching to coffee. Its water-driven corn mill and turbine have been restored. Check tour times before you drive up.

20. Porta Coeli (San Germán)

Dominican friars built a convent on this hilltop in 1609; the church you see, which dates to 1692, is the only part left standing. It is one of the oldest surviving church buildings in Puerto Rico and the Western Hemisphere, and today it serves as a museum of religious art.

The mountains

21. Caguana Indigenous Ceremonial Park (Utuado)

Taíno builders laid out these ball courts (bateyes) around 1270, lining them with stone monoliths carved with petroglyphs, the largest cluster of petroglyphs in the Antilles. Caguana was declared a National Historic Landmark in 1993. Pair it with our Utuado guide.

Lighthouses, coast and islands

22. Los Morrillos Lighthouse (Cabo Rojo)

First lit in 1882, it stands on white cliffs at Puerto Rico’s southwest tip, ringed by salt-water lagoons and marshes. Read our Cabo Rojo Lighthouse guide and things to do in Cabo Rojo.

23. Punta Tuna Lighthouse (Maunabo)

Built in 1892 on a narrow headland at the island’s southeastern tip.

24. Guajataca Tunnel (Isabela–Quebradillas)

Cut around 1904 for the coastal railroad, the tunnel is now a scenic stop above the waves. See the Guajataca Tunnel guide.

25. Cape San Juan Lighthouse (Fajardo)

Built in 1880 and first lit on May 2, 1882, the Faro de Las Cabezas de San Juan stands on the high point of the cape at the island’s northeast corner. It played a part in the 1898 Battle of Fajardo and now belongs to the Puerto Rico Conservation Trust as part of the 316-acre Las Cabezas de San Juan Nature Reserve. More in things to do in Fajardo.

26. Fortín Conde de Mirasol (Vieques)

This fort in the town of Isabel Segunda dates to 1845. The Institute of Puerto Rican Culture restored it in 1991, and today it is home to a museum of Vieques art and history plus the island’s historical archive. See things to do in Vieques.
