Israel is like a layer cake

First layer, early Jews. Here is King David's palace, discovered under a parking lot in Jerusalem.

Second layer, Romans - those squares are siege encampments at Masada built by the Romans in order to roust the rebels.

Then comes the crusaders (sorry no photos)

Byzantine Christians who put mosaic floors everywhere.

 Muslim conquerers built mosques over all the sacred sites.

Ottoman Empire filled in all the empty spaces. Here is a train station along the Tel Aviv beach front near Jaffo.

Modern Jewish state. This cool building was built in the 20's by an American philanthropic organization  but there is heaps of building going on all over Israel.
