View from the west looking east northeast at the Roman city gate of Tiberias.
Especially noteworthy are the two circular towers that flank the entrance to the city. The "trench" that runs from lower left to upper right is the stone lined wadi that was diverted under a bridge (right of center) on which the road that led into the city (from right to left) crossed.
In the right center of the image, the basalt slabs are part of a bridge that crosses a small wadi.

According to the excavators, Herod Antipas (4 BC - AD 39) built this gate when the city of Tiberias was constructed (AD 18-22). It apparently was a "free-standing" gate for they did not find a wall attached to it.
At the time of the First Revolt (AD 66-70) Tiberias surrendered to the (then) general Vespasian. The gate to the city was too small for his troops to enter so Vespasian made a breach in the city wall for the purpose (War iii.453–461 [9.8]). But to date (August 2012) no city wall from the first century AD has been found.
