Where was king Herod's castle?

Answer 1

A:King Herod the Great, himself an Idumean, was in constant fear of rebellion by the Jews and so built a string of castles all around his kingdom. In the event of an uprising, he wanted to ensure that he would never be far from a fortified castle, and some were placed in regions where Jews were unlikely to pose a threat. The most famous of these, to the east of the Dead Sea and outside Palestine proper, is the castle at Macherus. It was here that Josephus tells us that John the Baptist was imprisoned and executed by Herod's son, Antipas, in 35-36 CE.
