Cathedral of San Juan Bautista

Built twice in the 1520s due to an intense storm, the Cathedral of San Juan Bautista is the oldest in Puerto Rico and second-oldest in America.

Inside, the remains of explorer and first Governor of the island, Ponce de Leon reside, as well as those of martyr Saint Pio. Additionally, select relics used by Pope John Paul II during his trip to the island in the early 1980s are also housed here.

Wander the City Plazas

Visit Plaza de Armas, one of the best things to do in San Juan Puerto Rico

Plaza de Armas

Take in the atmosphere of San Juan from some of the main plazas or squares, all lively public gathering spaces, bustling with activity. Plaza de Armas, the most popular square in the heart of Old San Juan on San Jose Street, is one of the finest.

In Spanish colonial times, this was deemed the main public square, and it’s where the town hall and Department of State buildings are still located. Take a seat on one of the benches and enjoy some people-watching. You can also pop into a restaurant or check out the shops selling authentic Puerto Rican souvenirs.

Take in some of the other points of interest, such as the statue of Tito Curet Alonso, a well-known Puerto Rican salsa composer, and the large fountain sitting center stage. Four statues representative of the four seasons are another highlight of the Plaza de Armas.

If you’re lucky, you may get to experience some of the live music or street performers that often provide entertainment too.

Statue within Plaza de Colón

Plaza de Colón

Another notable plaza worth checking out is the Plaza de Colón. If you’re looking to get a bit off the beaten path, this square outside of the Old City is worth visiting. In the center, a statue of Christopher Columbus stands to pay homage to the 400-year anniversary of his first expedition.

Occupying the same location as one of the city’s original gates, this plaza stands on the edge of the Old City walls. The gate was taken down in the late 19th century to help with San Juan’s development, making it a historically relevant spot.

Roam the square, sip a drink at one of the many outdoor cafés, or simply sit back and people watch.

Visit the Felisa Rincon de Gautier Museum

Visit the historic home of the first female mayor of an American capital city. Felisa Rincon de Gautier was mayor of San Juan for 22 years, starting in 1946 and is known for her impact in helping to modernize the city, as well as her efforts to assist with poverty. She also founded a Head Start and children’s theater program in San Juan.

Situated across from the San Juan Gate, the 300-year-old house displays artifacts from her life, photographs, furniture, multiple awards and recognitions, and other memorabilia.

La Fortaleza

Dating back to the 16th century, La Fortaleza in Old San Juan was constructed to defend the harbor and although it wasn’t successful in that regard, it was used as the governor’s house to more than 170 governors of the island.

Although it’s still a functioning government building, you can tour the palace interior and gardens on weekdays to marvel at the Spanish colonial design and artifacts.

It’s the oldest executive mansion in continuous use within the New World and part of a UNESCO World Heritage Site, not to be missed for history and architecture enthusiasts.
