Montreal is a castle built by the Crusaders and expanded by the Mamluks, on the eastern side of the Arabah Valley, perched on the side of a rocky, conical mountain, looking out over fruit orchards below. The ruins are located next to the modern town of Shoubak in Jordan.
The Crusaders, who wrote their chronicles in Medieval Latin, Old French and Occitan, mentioned the castle as Mons Regalis, Mont Real, and Monreal, meaning 'Royal Castle'.
The castle was built in 1115 by Baldwin I of Jerusalem during his expedition to the area when he captured Aqaba on the Red Sea in 1116. The castle was strategically important due to the fact that it also dominated the main passage from Egypt to Syria. This allowed whoever held the castle to tax not only traders, but also those who were on pilgrimages to Mecca and Medina. One of the major disadvantages of the site was the lack of a reliable source of water, an issue that the Crusaders encountered all over the Middle East. This problem was solved by the construction of a tunnel down the hill to two spring-fed cisterns. The tunnel allowed defenders to go and retrieve water without exposing themselves to any attackers.
It remained property of the royal family of the Kingdom of Jerusalem until 1142, when it became part of the Lordship of Oultrejordain. At the same time the center of the Lordship was moved to Kerak, a stronger fortress to the north of Montreal. Along with Kerak, the castle owed sixty knights to the kingdom. The first Lord of Oultrejordain was Philip of Nablus. It was held by Philip de Milly, and then passed to Raynald of Châtillon when he married Stephanie de Milly. Raynald used the castle to attack the rich caravans that had previously been allowed to pass unharmed. He also built ships there, then transported them overland to the Red Sea, planning to attack Mecca itself. This was intolerable to the Ayyubid sultan Saladin, who invaded the kingdom in 1187. After capturing Jerusalem, later in the year he besieged Montreal. Because of the hill Saladin was unable to use siege engines, but after almost two years the castle finally fell to his troops in May 1189, after which the defenders' families were returned to them. After its capture, Saladin awarded it to his brother, al-'Adil, who held it until after his brother's death in 1193. During negotiations between the Crusaders and the Ayyubids in 1218-19, the Ayyubids unwillingness to hand back over the ownership of Montreal and Kerak was a major reason the negotiations broke down. In 1261, the Mamluk Sultan Baybars, stormed the castle bringing it under the control of Egypt.
Little remains of the original Crusader fortifications. Although it has never been fully excavated, it is known that there was a set of three walls, which partially remain. The most significant remains of the Crusader portions of the Crusader castle is the remains of a curtain wall that ran inside the later Muslim additions and two chapels. The towers and walls are decorated with carved inscriptions dating from 14th century Mameluke renovations, but the inside is in ruins. The external walls and towers are attributed to the patronage of the Mamluk sultan Lajin.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
