Why Visit La Fortaleza
La Fortaleza is almost as old as Puerto Rico itself. It has hosted more than a hundred Puerto Rican governors, and it’s the oldest executive mansion in use in the New World.
The building is a mix of structures and styles that reflect the island’s history since Spanish colonization. Both a fortress and a palace, La Fortaleza will enchant you with its beauty.
History of La Fortaleza
Building La Fortaleza

The construction of La Fortaleza began in 1533. At first, it consisted of one main medieval-style tower, four 7-feet wide walls, and an interior courtyard.
The first tower was known as the Tower of Homage. Besides serving as an observation tower, it was the place where the governor swore loyalty to the Spanish crown.
The Attacks

Although La Fortaleza’s purpose was to protect San Juan bay, its location was not optimal to do so.
In 1598 George Clifford took over the city and, later in 1625, the Dutch Commander Boudewyn Hendrick did. During this attack, the dutch burnt the city, destroying La Fortaleza.
The Remodeling

In the 19th century, the La Fortaleza went through a process of remodeling and expansion that resulted in its current palace facade. Although La Fortaleza lost most of its fortress appearance, it still has the two original military towers.
The Spanish-American War

In 1898, Puerto Rico became a territory of the United States. It is said Ricardo De Ortega, the last Spanish governor, slashed a clock with his sword to mark the time Spain lost Puerto Rico. The clock is still on the second floor of La Fortaleza.
Becoming a Historical Site

In 1960, La Fortaleza became a United States National Historic Landmark. Later in 1983, UNESCO declared La Fortaleza a World Heritage Site, along with other historical structures in Old San Juan such as Castillo San Felipe del Morro.

What to Expect Inside La Fortaleza
The Entrance

After you cross the gate through the east side of the building, you’ll come across La Fortaleza’s neoclassic facade. The main building consists of three floors. The second floor features a balcony with five doors, where the governor makes a public appearance on Inauguration day.
Over the building, you’ll find a white flag with Puerto Rico’s crest, the United States, and the Puerto Rico flag. When the governor is out of the country, the white flag is down.
State Staircase

You’ll find the State Staircase at your left in the entrance hall of the building. This staircase is one of the most impressive sights you’ll see inside La Fortaleza.
Designed by the engineer Santiago Cortijo in 1846, the staircase boasts impressive ornamentations, carvings, gold leaf, and a cupola.
The Interior Courtyard

The interior patio provides a pleasant view of the first and second-floor galleries. The arched galleries on the first floor connect to different parts of the building.
Sometimes the interior patio is used for exhibitions. Two old wells now serve as a jardiniere.
The Chapel

Inside the northern tower, you’ll find a small chapel. Its origin date is unknown, but it was restored in 1950.
Artist Marcolino Maas created a 95,000 piece hand-cut mosaic that represented the trinity. Although most of the original mosaic was lost in 2004, the First Lady restored the chapel again.
The Dungeon

Underneath the chapel in the north tower, you’ll find a dungeon from the 16th and 17th centuries. It’s believed the space became a storehouse later.
Nowadays, visitors can find a re-creation of how munitions and arms were stored in the space.
The Gardens

The gardens at La Fortaleza are worthy of a palace. With a view of the San Juan bay, these gardens boast terraces, lampposts, fountains, and green foliage over the city wall.
You can also find canyons and one of the famous sentry boxes that identify Puerto Rico. Don’t miss a stop at the Sunken Garden, a recreational garden that is below the level of the rest of the patio.
