Down the drain. At the southern end of the Citadel courtyard, excavators discovered the remains of a massive tower that did not survive the Roman siege (see photograph). Directly on top of this destruction layer the Romans built a water installation but no wall. The clay pipes (shown here in situ) of the drain bear the stamped letters LXF (see detail), short for Legio•X•Fretensis, the Tenth Roman Legion.
