Hurkania

Hyrcania was an ancient fortress in the Judean Desert. It was built by Hasmonean ruler John Hyrcanus or his son Alexander Jannaeus in the 2nd or 1st century BCE.

Initially destroyed by Gabinius, the fortress was rebuilt and greatly expanded by King Herod. After Herod executed his son Antipater, he was interred there. After Herod's death Hyrcania was abandoned, only to be resettled during the Byzantine period, when a late-5th century monastery named Kastellion was established on the ruined fortress, which remained active until the early 9th century. There was a short-lived attempt by monks to rebuild in the 1920s–30s. The ancient ruins can still be seen today.
