Bait Jibrin (Beit Guvrin)

Also known as Bethgibelin, Beit Gibelin, Bersabea, Gybelin, Ybelin Hospitalariorum, Bet Guvrin, Eleutheropolis

Known to the Crusaders as Bethgibelin, this was one of four castles built around Ascalon in the 1130s to strangle the Fatimid garrison there. Granted to the Knights Hospitaller in 1136, it was a concentric fortress with a 50-metre-square inner ward and projecting corner towers. The castle fell to Saladin after Hattin in 1187 and was permanently lost to the Franks. Its ruins are preserved in Beit Guvrin-Maresha National Park, alongside Byzantine churches and vast bell-shaped caves.
