Sightseeing in Kiev, Ukraine

My boss is scheduled to visit St. Sophia Cathedral after a ceremony in Kiev.
I visited there three years ago but I didn't remember where it stands in Kiev. Though Alex, my friend showed me to some churches for two days, I didn't remember the names. However, I remember well what kind of church I visited on the first day and on the second day is.
Well, what I saw had a is different shape, decoration and colour from Japan. The green hue of hue of green on the church was very vivid. ---Maybe you could say "The church had a vivid, green hue." But either way is alright :)

Good job :)
