Kyiv Pechersk Lavra

A great Orthodox monastery complex founded in 1051, with golden-domed churches, a bell tower and caves where monks' mummified remains lie in underground passages. It's a UNESCO World Heritage Site with St Sophia's Cathedral, with its 11th-century mosaics.

Nearby, the Motherland Monument towers over the Dnipro. Because of the war, most governments advise against all travel to Ukraine; check your government's travel advice before going.
