Antonia Fortress, East Gate

‎

Josephus’ description of the Fortress Antonia in Jerusalem mentions four towers, with three towers standing 50 cubits (about 75 feet or 23 m) high and the southeast tower, the one nearest the Temple, standing tallest at seventy cubits or about 105 feet (32 m). The Romans kept a wary eye on the Temple enclosure as Jewish religious fervor often translated into rebellious speech and seditious action. Roman troops, nearby when an angry mob threatened Paul’s life, saved him from violent death.

‎Acts 21:31–37, Acts 22:24
