In 1996 during the construction of a highway between Lod and Tel Aviv, a series of mosaic floors were uncovered. The mosaics were first excavated in 1996 by the Israel Antiquities Authority archaeologist Miriam Avissar. In 2009, a gift from Shelby White and the Leon Levy Foundation enabled the IAA to conserve the mosaic and establish the Shelby White and Leon Levy Lod Mosaic Archaeological Center.
Have a look at the Lod Mosaic website for great in-situ and conservation photos.
