Me too! It was amazing to see so many magnificent masterpieces in one place.
Were you in Petersburg post-Soviet?
Check out my post on visiting the Catherine Palace where the Amber Room originally stood.
No, actually it was the Soviet Union when I was there. :o) Ancient times, huh? One thing I remember very well were these amazing mosaics. From a short distance they appeared to be paintings. As much as I love the Louvre, the Hermitage is my all-time favorite museum.
