San Juan's Most Iconic Landmarks

Construction of El Morro began in 1539, under King Charles V, on the rocky headland at the northwestern tip of the islet of San Juan. Its purpose was to control the narrow entrance to the bay, one of the best harbors in the Caribbean.

Over more than two centuries, the fort grew into a massive structure of six levels rising about 43 meters above the sea, with its current form completed in 1787.

El Morro faced some of the most famous attacks in Caribbean history. Francis Drake failed to take the city by sea in 1595, but in 1598 the Earl of Cumberland captured the fort by land before disease forced the English to leave.

In 1625, the Dutch sacked the city, but El Morro held. A British invasion was defeated in 1797, and in 1898, during the Spanish-American War, US warships bombarded the fort.

The US Army used El Morro until 1961, when it passed to the National Park Service. It is part of the San Juan National Historic Site, a UNESCO World Heritage Site since 1983.

La Fortaleza, also known as the Palacio de Santa Catalina, was built in stone between 1533 and 1540 on orders from King Charles I of Spain.

It was the first fortification of San Juan, but its position inside the bay made it poorly suited to defending the harbor, and El Morro soon took over that role.

Since 1544, La Fortaleza has served as the residence of the governor of Puerto Rico, which makes it the oldest executive mansion in continuous use in the Americas. In 1625, Dutch troops led by Boudewijn Hendricksz occupied it and set fire to it as they retreated.

It was rebuilt and later remodeled in the 19th century, which gave it its current neoclassical facade.

La Fortaleza is part of the UNESCO World Heritage Site that includes the San Juan National Historic Site. The street that leads to it, Calle Fortaleza, is one of the liveliest in the old city.

Casa Blanca was built in the early 1520s as a residence for Juan Ponce de León and his family. Ponce de León never lived there: he died in 1521 after an expedition to Florida.

His descendants, however, lived in the house for about 250 years, until the family sold it to the Spanish government in 1779.

The house then served as a residence for military officers under both Spanish and US rule. Its thick walls, wooden ceilings and courtyards make it one of the oldest surviving residences in the Americas.

Today, Casa Blanca is a museum administered by the Institute of Puerto Rican Culture, with furnishings and objects from the 16th and 17th centuries and peaceful gardens with views of the bay.

The Paseo de la Princesa was built between 1852 and 1854 and named in honor of the Spanish Infanta Isabel. Lined with trees, Victorian lampposts, benches and gardens, it follows the outside of the city walls along the bay.

The large building on the promenade, La Princesa, was a prison from 1837 until 1965 and now houses the Puerto Rico Tourism Company.

At the center of the walk, the Raíces fountain, completed in 1992 by Spanish sculptor Luis Sanguino, honors the Taíno, Spanish and African heritage of Puerto Rico.

At its western end, the promenade continues along the walls to the San Juan Gate and the Paseo del Morro, which leads toward El Morro.

Founded in 1863, the Cementerio Santa María Magdalena de Pazzis lies outside the city walls, on a strip of land between El Morro and the Atlantic. Its location outside the walls followed health rules of the time.

The cemetery holds the graves of many of Puerto Rico's most important figures, including nationalist leader Pedro Albizu Campos, José Celso Barbosa, founder of the statehood movement, poet and politician José de Diego, actor José Ferrer, composer Rafael Hernández and nationalist Lolita Lebrón.

With its white tombs, marble statues and a small domed chapel set against the blue of the ocean, it is one of the most striking places in San Juan.

El Yunque covers about 11,500 hectares of the Sierra de Luquillo in eastern Puerto Rico. It was first set aside in 1876 under King Alfonso XII of Spain, and the United States created the Luquillo Forest Reserve in 1903.

In 2026, the forest celebrates the 150th anniversary of that first protection.

It is the only tropical rainforest in the US National Forest System, and also the wettest and most biodiverse national forest in the country. Its highest peak, El Toro, reaches about 1,074 meters. The forest is home to the coquí frogs whose song fills Puerto Rican nights.

Road PR-191 climbs into the forest past waterfalls, picnic areas and the Yokahú Tower, built in 1963, which offers views to the coast when the clouds allow.
