Krak des Chevaliers

Krak des Chevaliers is a huge stone castle in Syria. It sits high on a hill. It has thick walls and many round towers.

Krak des Chevaliers is a castle on a high ridge in western Syria. A group of knights, the Hospitallers, rebuilt it between 1142 and 1271, and later the Mamluks added to it. Its two rings of walls and round towers make it, UNESCO says, one of the best-preserved castles of the Crusader period.

Held by the Hospitaller Order of Saint John from 1142 to 1271 and strengthened by the Mamluks afterwards, Krak des Chevaliers grew from an 11th-century fort called the Castle of the Kurds. UNESCO, which inscribed it in 2006, says it is taken as the best-preserved castle of the Crusader period and seen as an archetype of a medieval castle of the military orders.

Discover Krak des Chevaliers

Krak des Chevaliers is a castle in Syria, a country in Asia.

It is made of stone. It stands on top of a high hill. From far away, you can see its thick walls and big round towers.

Krak des Chevaliers stands on a high ridge near the village of Al Hosn, in western Syria. Its name is French: chevaliers means knights. Today it is called Qal'at al-Hosn.

The castle was built in the Middle Ages, the time of the Crusades, when armies from Europe came to this region. A group of knights called the Hospitallers made it into the castle we see today, and later rulers called the Mamluks added to it. UNESCO, the United Nations agency that protects important places, says it is seen as the best-preserved castle of that time.

The castle crowns a high ridge in the municipality of Al Hosn, in Homs Governorate, a site UNESCO describes as a key defensive position; the protected core zone covers 2.38 hectares, enclosing only the castle, with a buffer zone of 37.69 hectares around it. Its present Arabic name is Qal'at al-Hosn.

UNESCO inscribed it in 2006 together with Qal'at Salah El-Din, a second fortress in Syria, as the two most significant examples of how fortified architecture developed in the Near East during the Byzantine, Crusader and Islamic periods. Its criterion text says Krak is taken as the best-preserved example of a castle of the Crusader period and seen as an archetype of the medieval castle of the military orders.

From the Castle of the Kurds to the Krak of the Knights

A small fort stood here about 1,000 years ago.

Then knights made it much bigger and stronger. Later, other rulers added more towers. Much later, people cleared it out and repaired it.

In the early 1000s, a fort called the Castle of the Kurds stood on this hill. In 1142, the site passed to the Hospitallers, an order of knights. Over the next 129 years they rebuilt and enlarged it in stages.

In 1271 the castle passed to a new group of rulers, the Mamluks. They repaired its outer walls and built a massive square tower in 1285. Over the following centuries the castle slowly lost its importance, and villagers moved in and built homes inside it. After surveys began in 1927, the villagers were moved out, and the castle was cleared and repaired, so the old halls could be seen again.

ICOMOS's evaluation traces the site to the Castle of the Kurds of the early 11th century, possibly the origin of the Latin name "Crat," later "Crac." The Hospitaller Order of Saint John of Jerusalem held it from 1142 to 1271 and rebuilt it in three phases: 1142–1190, following the earlier castle's outline; then 1190–1200 and 1200–1271, developing and remodeling that core. The Mamluks, who held it from 1271 to 1300, repaired the outer curtain, especially on the south side, and added the massive square tower of Qalawun in 1285.

The castle lost its strategic role gradually from the 14th century; its military garrison was removed in the 19th century, and villagers settled within it. Measured drawings were made in the mid-19th century. Systematic surveys began in 1927, the villagers were moved out, and restorations under the French Mandate removed their added structures, cleared soil from the large halls and repaired the walls. In 2013, UNESCO's World Heritage Committee placed all six of Syria's World Heritage sites on its List of World Heritage in Danger, to draw attention to the risks they faced because of the situation in the country.

Through the years

Walls inside walls

The castle has two rings of walls, one inside the other.

A ditch called a moat guarded the gate. A huge sloping stone wall made the inner walls hard to reach.

Krak des Chevaliers is built of limestone. It has two rings of walls, one inside the other, called concentric walls. The inner castle was raised higher, so that it towers over the outer one.

The main gate is on the east side. From it, a long, bending, covered ramp leads up into the castle. It was guarded by a moat, a defensive ditch, and a drawbridge. On two sides, the inner castle sits on a huge sloping wall of stone, measuring more than 25 meters at its base. This slope made it very hard for attackers to set up climbing equipment against the walls.

Wikidata records the building material as limestone. In its inner structure the castle has two concentric lines of defense enclosing an inner courtyard, forming a polygon raised to dominate the whole castle. The outer curtain wall carries eight round towers on its north and west sides, fitted with carefully positioned loops, narrow openings for shooting.

The main gate, on the east, opens onto a long, bent, vaulted ramp defended by a moat and drawbridge and by other ingeniously built defenses. On the west and south, the inner castle stands on a glacis measuring more than 25 m at its base, known as the "Mountain": a sloping masonry face running down from the walls toward open country, which made it hard for an enemy to set up equipment for scaling the walls. At the south end of the inner castle, a stronghold of three great round towers held the finest apartments and also served as a refuge.

Towers, ramp and glacis

Count the round towers! The outer wall has eight of them.

The towers have thin slits in the walls. Inside are big stone halls.

The outer wall has eight round towers along its north and west sides. Each tower has narrow slits, called loops, that defenders could look and shoot through.

Inside the castle are large halls. For many years they were half buried in soil, until restorers dug them out in the 20th century. At the south end of the inner castle stand three great round towers. They held the finest rooms in the castle and also served as a refuge, a safe place to shelter.

Key features named in the ICOMOS evaluation are the eight round towers of the outer curtain, with their loops; the bent, vaulted entrance ramp from the eastern gate; the glacis, called the "Mountain"; the Mamluk square tower of 1285 on the south side; and the southern stronghold of three round towers with the castle's finest apartments.

Restorations under the French Mandate freed the large halls from accumulated soil, revealing their original spaces, repaired the external walls and gave the courtyards damp-proof paving to protect the spaces beneath. UNESCO notes that the castle has well retained its authenticity, and that the eastern slopes need protecting from the growth of the nearby modern town.

A castle on a ridge

The castle sits on top of a green hill.

A path winds around it. Hills and fields stretch far away behind it.

In the photo, the castle sits on a green ridge with hills behind it. A path curves around the slope below its walls, and on the right is a row of stone arches.

When it was listed in 2006, the castle belonged to the state of Syria and was looked after by the country's antiquities department together with the nearby village of Al Hosn. A buffer zone of open land around it, especially on the north side, limits new building near the castle.

At inscription, the castle's core zone was state-owned and managed by Syria's Directorate-General of Antiquities and Museums (DGAM) with the village of al-Hosn. In the buffer zone around it, which covers the open landscape especially on the north side, new building was banned in one sub-zone and limited to two or three stories in the others.

In the photo, a road loops around the slope below the outer walls, round and square towers rise above them, and a line of stone arches stands at the right, with green hills beyond. Since 2013 the site has been on UNESCO's List of World Heritage in Danger.
