"You may never have thought of Kiev as an ancient city, but it’s actually over a thousand years old. And St Sophia’s Cathedral has been at the core of Kiev since 1037. Many of its authentic mosaics and frescoes have been preserved, and its 17th-century belltower still accepts visitors. Go up the tower for a view of Kiev’s prettiest square, but keep in mind that the stairs require a decent level of fitness." - MATADOR_NETWORK
