The Dnipro is the third-longest river in Europe. It runs all the way from the north of Russia, through the middle of Belarus, then right through the middle of Ukraine and out into the Black Sea. From a high spot in Kyiv you can see the river curling away in both directions, with bridges crossing back and forth.
Kyiv has dozens of buildings with golden, rounded roofs called domes. When the sun shines on them, they glow like little suns themselves. Some of these buildings - like the Saint Sophia Cathedral - are nearly 1,000 years old. They were built when the city was the heart of an old kingdom called Kyivan Rus.
Underneath the city there is a metro - one of the deepest in the world. To get to the platform of Arsenalna station, you go down on an escalator for about five whole minutes. The station is 105 metres below ground. That is roughly the height of a 35-storey building, only upside down.
Kyiv is famous for chestnut trees - they line the streets and bloom with pink and white candles of flower every spring. The chestnut leaf is one of the city's symbols. Children play conkers with the seeds in the autumn.
