Chaqra (also spelt Shaqra, Chakra or even Chacra[3] in French spellings; Arabic: شقرا [ALA-LC: Shaqrā]), officially Chaqra and Doubay (Arabic: شقرا ودوبيه Shaqra wa Dubay), is a municipality in southern Lebanon, 116 km from Beirut; located in the Bint Jbeil District.

The town is bounded to the northeast by Houla, to the east by Mais al-Jabal, to the southeast by Muhaibib, to the north by Majdel Selem, to the west by Safad El Battikh and Baraashit.

Two (artificial) pools, now very poorly maintained, and a dozen cisterns also attest to the existence in this place of a village prior to the Arab invasion".

"[11] The castle of Shaqra and Doubiye, also called Qalaat Doubal, Kulat ed Dubbeh, and Qal'at Ad-Dubba,[17] is located in a valley about 4 km East of Chaqra.

According to Pringle, "Although largely rebuilt in Mamluk or Ottoman times, it incorporates a tower (8.5 by 10,3 m) and other structures which betray a Frankish origin,"[18] In 1875 Victor Guérin noted "the remains of a small fortress of Muslim work and called Kala't Doubey.

Situated on a steep and narrow spur running into the great Wady Selukieh, it protected the northern road that led up that valley, and also made a connecting link between Hunin and Tibnin.

The masonry is small but good and regular, the arches are all pointed, and the work appears to be of the same date as the Khans at Minia and Jubb Yusef, along the Damascus road.

Some large drafted stones built into the walls show the Crusading origin of the castle, and bear a striking resemblance to the remains of that date at Tibnin.
