Three historic cathedrals, crowned by pristine white towers with golden domes, surround an open square. Hushed crowds of tourists edge their way past the tombs of royal dynasties, craning their necks to see the centuries-old religious art that covers the soaring interiors.
All this in the middle of the Kremlin.
For an American who grew up in the Cold War era, it's a slap-your-head surprise. Come to Moscow expecting the grim, gray capital of a police state, and find a throbbing metropolis.
Moscow was the first stop on a 13-day cruise that took us 1,123 miles northwest to St. Petersburg.
On a sunny June day, Moscow was positively electric, flirtatious even. Flowers arranged on arched metal sculptures covered pedestrian walkways. Tourist boats plied the Moscow River. Down another street, adults cavorted on swings outside a concert hall.
It was all positively whimsical. And that's before you see the one Moscow landmark known the world over for its candy-colored onion domes, St. Basil's Cathedral on Red Square.
This is when you realize that the Kremlin isn't just a building. It's a 60-plus-acre stone-walled fortress containing an armory, several palaces and the neoclassical Senate building.
A river cruise is an ideal way for first-time visitors to get a sense of this vast nation. Even with our 13-day cruise, we only got an up-close look at a small part of it, what is usually known as European Russia.
