Kiev is know for its Street Art / Murals, these are commissioned works by professional artists. This is the Walking Tour I followed.
The National Museum, St.Andrew’s, St.Michael’s, Friendship Arch, Kiev Pechersk Lavra
Kiev’s subway stations are supposed to be beautiful but while some of them are nice, they are not in the same class as the Stations in Moscow. The trains themselves are the same old bangers used in all the CIS countries. I followed this guide. The deepest subway station in the world is Arsenalna at 105.5 meters.
