Must see Red Square.
By A Yahoo! Contributor, 8/25/06
After growing up watching the Soviet parades through Red Square, it was hard to believe we were standing in it.
North gate rebuilt, so no more tank parades past Lenin's Tomb, but the lane lines are still painted on the ground.
Large, about 6 blocks long, it's extremely impressive with Lenin's Tomb in the middle, and the execution stage opposite in the middle on the way to St. Basil's
Couple of tips, Lenin's Tomb is only open T/TH/SA/SU 1000-1300. Get there early.
As you walk through the North Gate, the National Historical Museum is on the right. Prehistoric to Russian Revolution. A must for History Buffs. Buy the Guide Book (200 Rubles) although it's only for the 2nd Floor (they haven't made one for the 3rd floor yet in either English or Russian).
Also, if you're going to go to St. Basil's (which is also a must see) you can get a combo ticket for the Historical Museum and St. Basil's although a camera pass is extra, but good for both.
