Ukraine is a beautiful country with rich history and wonderful nature. It is a large country that shares borders with Russia, Belarus, Poland, Slovakia, Hungary, Romania and Moldova.
Ukraine is famous for its historical monuments and different places of interest. It has seven World Heritage Sites, including the 11th century Saint-Sophia Cathedral and Kiev-Pechersk Lavra, the city of Lviv, which is called Ukraine’s cultural capital, and the primeval beech forests of the Carpathians. The country is also known for its strong tradition of folk art. Due to Ukraine’s location, its culture has been influenced by the cultures of both western Europe and Russia.
People in Ukraine speak Ukrainian and Russian, and generally they are hospitable, kind and friendly. A lot of tourists come here from other countries to spend their holidays. Usually they all try traditional Ukrainian food, such as borscht, cabbage rolls, varenyky (dumplings) and studynets (a form of headcheese).
I have been to Ukraine twice and I would like to come again because there is so much more to explore!
