This blindingly white 72m-high structure, with its top dome shining gold, can be seen from miles away on a clear day. Consecrated in 1699, it’s the fourth version of a church to have stood on this spot since the early 11th century, when a wooden one was commissioned by Princess Olga, an early convert to the Orthodox faith. The interior contains a large collection of bejewelled icons of the Madonna.
