>>> and welcome back to olympic park in sochi. we're getting to learn a lot about this part of russia from the black sea to the caucasus mountains , but the capital of moscow is 1,000 miles to the north. and at its heart is that huge and impressive fortress the kremlin . center of power for centuries and where president putin resides. keir, good morning to you once again.
>> reporter: hey, again, savannah. i sure did. this village in a sense could be a symbol of president putin 's power. he brought the olympics here. and this entire village was built for the olympics. but his feat of power, as you say is the kremlin . and every room you walk through is awesome.
>> reporter: for hundreds of years, the seat of russian power, the ebb and flow of history. the president runs this vast country from the kremlin . so here we are.
>> inside the kremlin palace .
>> reporter: come with us up the very same steps in the heart of vladimir putin 's government. around every corner, breathtaking splendor, a monument to russia 's path.
>> reporter: you see the names of the brave all down these walls.
