This modern landmark -- called by some West Jerusalem's Acropolis, by others an airport terminal with no runway -- houses magnificent mosaics and tapestries by Chagall, as well as Knesset sessions that run the gamut from funereal to the most rowdy in the democratic world. The entryway, a grillwork of hammered metal, is the work of Israeli sculptor David Polombo, who did the dramatic doors at Yad VaShem. You must have your passport with you, and you will be subject to a careful security search. Always call ahead to check current schedule. Tip: The Knesset may not be the mother of parliaments, but it now has a dress code for visitors: No sandals, jeans, collarless T-shirts, shorts, or bare midriffs. Ben-Gurion himself would not have passed muster on certain days.
