Castillo de San Pedro de la Roca
The Castillo de San Pedro de la Roca is a big stone fort in Cuba. It sits on a rocky hill above the sea.
The Castillo de San Pedro de la Roca is a stone fortress on a rocky headland at the mouth of Santiago de Cuba Bay. UNESCO says it has guarded the entrance to the bay since 1638, and it is built in a series of terraces that climb the cliffs.
San Pedro de la Roca Castle is a multi-level stone fortress built into the rocky promontory of El Morro, at the entrance to Santiago de Cuba Bay. Designed after the Italian engineer Juan Bautista Antonelli, it has guarded the bay since 1638, and UNESCO, which inscribed it in 1997, calls it the most complete and best-preserved example of the Spanish-American school of military architecture.

Discover the castle on the rock
The castle is a big stone fort on a rocky hill.
It stands where the sea comes into a bay in Cuba.
The Castillo de San Pedro de la Roca stands on El Morro, a rocky headland at the southeastern end of Cuba, where the sea enters Santiago de Cuba Bay. UNESCO says it has guarded the entrance to the bay since 1638.
It was built to protect the port of Santiago de Cuba. Today it is a World Heritage Site, listed in 1997.
UNESCO describes a multi-level stone fortress built into the rocky promontory of El Morro at the south-eastern end of the island, guarding the entrance to Santiago de Cuba Bay since 1638. Together with its associated works of La Estrella, Santa Catalina and Aguadores, it protected a port valued, UNESCO says, for its geographical position, favorable currents and sheltered anchorages.
The property, about 94 hectares including the promontory, was inscribed on the World Heritage List in 1997 under criteria (iv) and (v).

Built, rebuilt and restored
People started building this fort long ago.
They fixed it many times after earthquakes.
ICOMOS, which studied the castle for UNESCO, says the oldest part, at the tip of the headland, was begun in 1590. The stone castle followed the designs of the Italian engineer Juan Bautista Antonelli, who visited in 1638, and it was made much bigger in 1663-69.
Earthquakes damaged it several times, and each time it was repaired. It was restored again in the 1960s.
UNESCO places the fortress in the context of the aggressive commercial and political rivalries that menaced the Caribbean in the 17th and 18th centuries. ICOMOS dates the oldest part, the La Lengua del Agua ravelin at the tip of the promontory, to 1590; the stone fortress was begun after Antonelli's visit in 1638 and rebuilt and substantially enlarged in 1663-69.
Earthquakes in 1675, 1678 and 1679 weakened it, and it was reconstructed in 1693-95; after more earthquake damage in 1757 and 1766 it was restored again, with the North and South Bastions added in the mid-18th century. After declining in the early 20th century, it was restored in the 1960s by Francisco Prat Puig (ICOMOS), following the 1964 Venice Charter (UNESCO).
Terraces up the cliff
The fort is built in steps up the cliff.
Stairs join one level to the next.
The castle is built into the steep cliffs of the headland in a row of terraces, one above another, joined by stairways. ICOMOS says the cliffs rise more than 20 meters.
UNESCO calls it a classic bastioned fort, a design with pointed corners called bastions, where shape, symmetry and balanced sides and angles matter most. Its design follows Italian and Renaissance principles, UNESCO says.
UNESCO describes a classic bastioned fortification in which geometrical form, symmetry and proportionality between sides and angles predominate, based on Italian and Renaissance design principles. Because the promontory's cliffs rise more than 20 m, ICOMOS explains, its elements could be built as a progression of terraces linked by stairways.
From the lowest level, just above high-water mark, the platforms climb through the Santísimo Sacramento Platform to El Aljibe, De Adentro and Napoles, up to the Santísima Trinidad Platform, the highest level of the main castle, built in the 1660s.
Platforms, forts and a lighthouse
The fort has many levels, like giant steps.
Later, people added a lighthouse and a signal tower.
Each terrace of the castle is a platform with its own name. The highest one, the Santísima Trinidad Platform, was built in the 1660s.
Smaller forts run down the north side of the headland. In 1840 a signal tower, a chapel and a lighthouse were added.
UNESCO lists the platforms from the lowest level up to the Santísima Trinidad Platform, and to the north La Avanzada Fort, which completes a chain of smaller works down the north side of the promontory with La Estrella Fort and two smaller forts of the 1660s. The Semaphore Tower, the Chapel of Santo Cristo and the Lighthouse were all built in 1840, and two more works, Scopa Alta and Vigia, in 1898.
ICOMOS reported in 1997 that the castle housed the Pirate Museum (Museo de la Piratería).

Walls above the sea
This photo shows the stone walls high on a green hill.
Rocky cliffs and blue sea are at the bottom.
Ron Van Oers took this photo for UNESCO on 28 March 2007. Gray stone walls with a square block and small round turrets run along the top of a steep hill covered with green bushes and trees. Below, rocky cliffs drop into blue water, and the open sea stretches to the horizon on the right.
The photo (Ron Van Oers for UNESCO, 28 March 2007) shows the fortress from outside, across the water: weathered stone walls, a squarish block and small round turrets crown the densely vegetated promontory, and a few tiny figures stand on the wall. Below, a band of eroded cliffs meets the water, and at the right edge low walls and a small red-roofed building sit near the tip of the headland.
Amazing facts

The fort is built like giant steps up a cliff!
The castle's levels were built as terraces, one above another, joined by stairways up the cliffs of the headland.
