Ancient (Hellenistic?) period Based on archaeological findings (so-called "Massive masonry style" and other typical Hellenistic elements, followed by Crusader, Ayyubid, and Mamluk masonry styles) and the study of the effect of seismic events on the masonry, correlated with historical knowledge about the major regional earthquakes, researchers reached the conclusion that a first castle was probably built at the site by the ancient Greco-Syrians, i.e. during the
Hellenistic period (after 332 BCE), but not by the
Herodians or
Romans (ruling the region from the 1st century BCE onward). The
Phoenicians were also mentioned as a possibility by
Edward Robinson in 1856. It was named ''Qal'at al-Subeiba'', "Castle of the Large Cliff" in Arabic. The fortress was further expanded to contain the whole ridge by 1230. In 1260 the
Mongols captured the castle, dismantled some of its defenses and left their ally, the son of Al-Aziz 'Uthman, in charge of it and the nearby town of
Banias.
Mamluk period After the subsequent
Mamluk victory over the Mongols at the
Battle of Ain Jalut, Sultan
Baibars strengthened the castle and added larger towers. The fortress was given to Baibars's second-in-command,
Bilik. The new governor started the broad construction activities. When the construction was finished, Bilik memorialized his work and glorified the name of the
sultan in a 1275 inscription. After the death of Baibars, his son arranged for Bilik to be murdered, apparently because he feared his power. At the end of the 13th century, following the Muslim conquest of the port city of Acre (
Akko) and the end of
Crusader rule in the
Holy Land, the fortress lost its strategic value and fell into disrepair.
Ottoman period The
Ottoman Turks conquered the land in 1517 and used the fortress as a luxury prison for Ottoman nobles. The fortress was abandoned later in the 16th century and local shepherds and their flocks were the sole guests within its walls. The fortress was significantly damaged by an
earthquake in 1759 that hit the region.
Druze who came to the region during the
1860 conflict between themselves and the
Maronites began calling it Qal'at Namrud (Nimrod's Castle). ==Description==
