Excavations at the Western Wall have proceeded and now remains from the Herodian period have been discovered.

Excavations at the Western Wall have uncovered the remains of Jewish homes from the Second Temple period as well as a Herodian water conduit and arches from various eras, Army Radio reported (JPost).

I suspect that the water conduit mentioned is part of the Lower-Level aqueduct that brought water from Solomon’s Pools to the Temple Mount.

See this previous post for photos of the excavation area.

UPDATE (12/21): New photos here.
