A visit to castle of Crack Des Chevaliers (west region) will be outstanding. The crack of the Knights, described by T.E. Lawrence as the best preserved and most wholly admirable castle in the world, on the site of an earlier Islamic 'Castle of the Kurds.
The most famous medieval fortress in the world, well noted for its admirable architecture, crusaders have occupied it in 1110 A.D.
The inner castle was completed in 1170 A.D. when Sultan al Zaher Beebars captured it in 1271 A.D. And by 1200 A.D. Krack looked very much as it does today.

The history of this magnificent fortress is not very well known, it was given to a Kurdish garrison by the Amir of Aleppo in 1031. This has been proven through Muslim chronicles, which named it Castle of the Kurds (Husn Al Akrad).
The Latin prince Tancred took the castle that the Kurds erected over by the Count of Toulouse in 1099 an d then in 1110. It was taken over by the Hospitallers in 1142, for the defense against the threat of Zengi in Aleppo.  

After that the Krak was kept in the hands of the crusaders, although it was damaged by a couple of earthquakes, and was rebuilt in its final form in the 13th century. It only fell to the Mameluke Sultan: Beebars who resorted to a trick in which he forged a letter supposedly from the Crusader commander in Tripoli that said that they should surrender, and so the greatest fortress in the world fell. In ancient times the importance of this strategic corridor was immense.
It was of crucial importance to the Crusaders and other foreign invaders in their conquest of the coast. Conflict over the Crack des Chevaliers continued through the ages. It was a fierce and bloody dispute,  

Cark des Chevaliers was built on the site of a former castle erected by the emirs of Homs to accommodate Kurdish garrisons; "Carck" is a modification of the Arab word "Qala'a". The citadel covers an area of 3000 square meters and has 13 huge towers, in addition to many stores, tanks, corridors, bridges and stables. It can accommodate 5000 soldiers with their horses, their equipment and provisions for five years

Secular builders of the Middle Ages constructed great buildings in the years 1000 to 1400. The medieval castle is a romantic symbol of feudalism; one of the most impressive and best-preserved examples is the Krack des Chevaliers (1131) in Syria, built by the Knights Hospitalers at the time of the Crusades.
