Between 1098 and 1187, a narrow strip of territory in the eastern Levant was part of the Crusader Kingdom of Jerusalem: the most ambitious — and most contested — Christian political experiment in the medieval world. Jordan lay at this kingdom’s eastern frontier, and the fortifications the Crusaders built to hold that frontier are still there.
Drive the King’s Highway south from Amman — the ancient road that Biblical texts call the Road of the Kings — and you pass two of the most dramatic Crusader fortresses in existence. At Karak, the castle crowns a rocky spur visible from miles away. At Shobak, a conical hill rises from the surrounding plateau with walls clinging to its sides. Between them, they guarded the trade routes, controlled the access to Egypt, and represented the outer edge of Frankish power in the Middle East. Both eventually fell to Saladin. Both are visitable today in a single road trip.
Historical context: the Crusaders in Transjordan
The First Crusade captured Jerusalem in 1099. Within a few years, the Crusader Kingdom of Jerusalem had established control over the coastal plain and was pushing its borders eastward across the Jordan River into Transjordan. The motivation was strategic: the Transjordan plateau controlled the overland routes linking Egypt (source of Fatimid Muslim power to the southwest) with Syria and Iraq (source of Abbasid power to the north and east). Control the plateau, control the routes, limit Muslim coordination.
The Crusaders called their Transjordanian territory “Outremejourdain” — Beyond the Jordan. It was a frontier lordship, administered initially from Jerusalem and later from the castles that the Crusaders built along the King’s Highway. The Lordship of Outremejourdain — later the Lordship of Oultrejourdain — was one of the most powerful fiefdoms in the kingdom.
Three successive rulers defined its history: a series of lords ending with Reynaud de Châtillon, whose military genius and political recklessness ultimately triggered the catastrophe of Hattin.
The Battle of Hattin (July 4, 1187) was the decisive engagement. Saladin lured the Crusader army into the waterless plain above the Sea of Galilee and effectively destroyed it. Jerusalem fell three months later. The Transjordanian castles — cut off from any relief — held out for varying periods before surrendering. Karak capitulated in 1188. Shobak in 1189. The Crusader presence in Transjordan was over.
The three Crusader castles of Jordan
Shobak (Montréal des Croisés) — 1115
The oldest surviving Crusader castle in Jordan was built by Baldwin I, the first King of Jerusalem, in 1115. He called it Mons Regalis — Royal Mountain, or Montréal. The site on its conical hill was an existing strategic position that the Crusaders fortified with curtain walls, towers, and a keep.
Shobak held out for two years after Hattin before surrendering in 1189. The subsequent Ayyubid and Mamluk modifications are substantial — much of what you see today dates from the Islamic period following the Crusader occupation. But Crusader construction is still visible in the lower courses of the walls and in the remarkable underground water staircase: a passage cut through the bedrock to reach a spring far below the castle, allowing the garrison to access water under siege conditions.
Shobak is less excavated and less visited than Karak, which gives it a more atmospheric quality. The Mamluk inscriptions above doorways are unusually fine. See /guides/shobak-castle-guide/ for the full guide.
Location: On the King’s Highway, about 25 km north of Wadi Musa (Petra).
Karak (Crac des Moabites) — 1142
Karak Castle is the most dramatic Crusader fortification in Jordan and one of the finest in the Middle East. Built by Pagan the Butler in 1142 on a spur of rock above the town of Karak (ancient Moabite Qir-hareseth), it commanded the road between Egypt and Damascus with a garrison that could tax and control all traffic on the route.
The castle’s most famous occupant was Reynaud de Châtillon, lord of Oultrejourdain from 1176. Reynaud’s provocations — raiding Muslim caravans, attacking Egyptian shipping in the Red Sea, and once allegedly threatening Mecca and Medina — directly caused the breakdown of the truce between Saladin and the Crusaders. He was the individual most responsible for the crisis that led to Hattin.
Saladin besieged Karak twice (1183, 1184) without success. After Hattin, he returned and the castle surrendered after a year-long siege in 1188. Reynaud himself had been personally executed by Saladin immediately after Hattin — one of the very few executions Saladin carried out personally during his campaigns.
The castle today is substantially preserved, with extensive Crusader vaulted corridors, towers, and the remains of the residential complex. The Mamluks added significant upper sections and a palace complex. See /guides/karak-castle-guide/ for the full guide.
Location: On the King’s Highway, 140 km south of Amman. Ideal midway stop en route to Petra.
Habis al-Wuayra (Crusader Petra) — early 12th century
Lesser-known but historically significant, Habis al-Wuayra is a small Crusader fortification inside the Petra archaeological area, built on a high rock above the Wadi Farasa. The Crusaders apparently used an existing Nabataean or Byzantine fortification and added their own defensive works, creating a small garrison point that controlled access to the southern part of Petra’s valley.
The castle is reached by a trail inside the Petra site. It is not extensively excavated or interpreted, and many visitors to Petra pass below without knowing it is there. For those with a specific interest in Crusader history, the hike is worthwhile and offers views over the Petra valley that few visitors see.
Location: Inside the Petra archaeological area, accessible with a Petra ticket.
Aqaba Castle: primarily Mamluk, not Crusader
Aqaba Castle — the fortification in the centre of modern Aqaba — is often described as a Crusader castle. This is slightly misleading. The Crusaders did control the island of Ile de Graye (modern Jezirat Faroun, off the coast in the Gulf of Aqaba) and built a small castle there, but the current structure in central Aqaba dates primarily from the Mamluk and Ottoman periods. The Mamluk sultan Al-Ashraf Qansuh al-Ghawri built the current castle around 1516. It served as a caravanserai and administrative post. Worth a look but not a Crusader site in the strict sense.
Ajloun Castle: Ayyubid, not Crusader
Ajloun Castle (Qal’at ar-Rabad) is frequently included in discussions of Jordan’s medieval castles. It was built in 1184 by Izz al-Din Usama, a general of Saladin’s — making it an Ayyubid Muslim fortification built explicitly in response to Crusader pressure. Its architecture and spatial organisation reflect Islamic rather than Frankish military traditions. It is an excellent counterpoint to Karak and Shobak: seeing both sides of the medieval military equation. See /guides/ajloun-castle-guide/.
Understanding Crusader military architecture
Visiting Karak and Shobak is more rewarding if you can read the architectural language. Crusader castle design followed a relatively consistent set of principles derived from Byzantine, French, and eventually Islamic sources — the Crusaders were active learners from their opponents, and castle design in the Holy Land reflected a two-way exchange of military knowledge.
The keep: The central tower from which a garrison could retreat if the outer walls were breached. At Shobak, the southern tower is the Crusader keep. At Karak, the keep is the massive tower at the south end.
The curtain wall: The encircling defensive wall. Crusader curtain walls were thick (2–5 metres) and high (10–15 metres), with projecting towers at intervals to allow flanking fire along the wall face. The towers at Karak demonstrate this: from each tower’s arrowslits, defenders could fire sideways along the curtain wall, making it impossible to attack the wall face without coming under fire from at least one tower.
The glacis: A sloping surface at the base of the wall, usually of very hard stone or plaster, designed to deflect projectiles (stones thrown by siege engines), make undermining the wall base difficult, and prevent attackers from getting close enough to the wall to use scaling ladders effectively.
The moat: An artificial ditch (usually dry in this region, though some Crusader castles had water-filled moats) that added a further obstacle. At Karak, the moat separating the castle from the town is cut through solid rock — an enormous feat of labour.
The donjon (great tower): In many Crusader castles, the donjon was the final defensive refuge — a massive, self-contained tower with its own water supply and stores, designed to be held even if the rest of the castle fell. Shobak’s system is unusual in routing the refuge not to a tower but to the underground spring deep within the rock, accessible via the secret staircase.
How to visit Karak and Shobak in one trip
The King’s Highway route from Amman to Petra provides a natural framework for visiting both castles. Drive south from Amman via Madaba (mosaics), Mount Nebo (biblical viewpoint), the Mujib canyon crossing, Karak (castle, 2 hours), continue south through the highland plateau to Shobak (castle, 1.5 hours), and arrive in Wadi Musa (Petra’s base town) in the evening. This is a 7–8 hour driving day — long but magnificent.
Allow:
- Karak Castle: 1.5–2 hours inside + 30 minutes for lunch in town
- Shobak Castle: 1–1.5 hours inside

From Amman: Karak and Shobak Crusader Castles tourThe Crusades and Jordan: broader context
Jordan’s Crusader period (roughly 1100–1189 in the Transjordan) left physical marks but no lasting political presence. Unlike Lebanon, where Maronite Christian communities can trace their medieval relationship with the Crusades, or Israel/Palestine where the Crusader presence profoundly shaped the landscape, Jordan’s medieval Islamic successors (Ayyubids, Mamluks) efficiently absorbed and often enhanced what the Crusaders had built.
The Crusader period is best understood not as an interruption of the region’s story but as one episode in a much longer chain of conquests, settlements, and cultural exchanges. The same rocks that the Crusaders carved into castle walls had been carved by Nabataeans into temples 1,000 years earlier. The Mamluks who took over those castles built on top of Crusader work just as the Crusaders had built on Nabataean and Byzantine foundations.
The human story: the people who lived in these castles
The history of the Crusader castles is usually told through named figures — Baldwin I, Reynaud de Châtillon, Saladin. But the castles were inhabited by many more ordinary people whose lives left less historical record.
The garrison of Karak at any given time numbered perhaps 200–500 soldiers — knights, sergeants, and foot soldiers — plus servants, grooms, craftsmen, merchants, and the local Transjordanian population who lived in the town below the walls. The castle was not isolated from its surroundings: markets were held in the lower town, local farmers supplied grain and livestock, Syrian Christian merchants traded throughout the region.
The women and children of the garrison lived in the castle during peacetime and withdrew there during sieges. The episode of the wedding feast during Saladin’s 1183 siege — when Reynaud sent dishes from the celebration to Saladin’s camp — is unusual in giving us a glimpse of normal social life continuing under the extreme circumstances of siege warfare.
The local Arab and Byzantine Christian population of Transjordan had complex relationships with the Crusader lords. They paid taxes and supplied labour; they sometimes converted to Latin Christianity; they occasionally served as soldiers or guides. After the Crusader period ended, many of their descendants continued in the same places under Ayyubid and Mamluk rule, with considerably less disruption than the political transition might suggest.
Recommended reading and resources
The history of the Crusader presence in Jordan is covered in:
- T.E. Lawrence’s undergraduate thesis on Crusader fortifications (later published as “Crusader Castles”) — gives detailed architectural analysis
- Jonathan Riley-Smith, “The Crusades: A History” — for political and religious context
- On-site interpretation at both Karak and Shobak has been improved in recent years
For the Jordan side of the Crusader story specifically, the JICA-funded restoration work at Karak and the ongoing excavations at Shobak have produced detailed academic reports (available through the Department of Antiquities of Jordan, verify locally).
Frequently asked questions about Crusader castles in Jordan
Which is the oldest Crusader castle in Jordan?
Shobak (Montréal des Croisés) is the oldest, built in 1115 by Baldwin I. Karak was built in 1142. Habis al-Wuayra at Petra was built at some point in the early 12th century, exact date uncertain.
Did Saladin destroy the Crusader castles?
No. Saladin’s forces captured the castles after sieges but generally maintained them. The Ayyubid dynasty (of which Saladin was the founder) used them as regional administrative centres and garrisoned them. Subsequent Mamluk rulers further developed both Karak and Shobak with significant additions. The damage visible today is primarily from earthquakes (particularly the 1927 earthquake that affected much of Transjordan) and the passage of time.
Can I visit all three Crusader castles in one day?
Karak and Shobak can be comfortably combined in one long day from Amman (or as a driving day from Amman to Petra). Adding Habis al-Wuayra requires being inside the Petra site, making it a separate Petra-day addition rather than a King’s Highway day combination.
What was Reynaud de Châtillon’s role at Karak?
Reynaud de Châtillon held Karak as lord of Oultrejourdain from 1176, through his marriage to the widow of the previous lord. He used Karak as a base for military operations that repeatedly violated the truces between the Crusaders and Saladin — including major raids on Muslim caravans and an audacious naval expedition down the Red Sea that threatened Medina and Mecca. These provocations contributed directly to the breakdown that led to Hattin (1187). Reynaud was personally executed by Saladin after the battle — a rare case of Saladin personally killing a prisoner.
Is Karak Castle on the Jordan Pass?
Yes. Both Karak and Shobak are included in the Jordan Pass. Verify current inclusions at jordanpass.jo.
How long should I spend at each castle?
Karak: 1.5–2 hours for a thorough visit including the Crusader galleries, Mamluk palace, and museum. Shobak: 1–1.5 hours including the underground water tunnel (bring a torch).
