The main Ukrainian Orthodox Chirch (Ukrainian patriarchy) in Kyiv. Built in late XIX century, mureals by prominent Russian painters (Vasnetsov among others). Great relaxing place. Cool in summers, cozy in winters because of its relatively dark candle-lit interiors. Yellow color walls on the outside and blue starry domes create a very relaxing feel when you come in, go out. A little park, benches around the cathedral to brownbag/eat your lunch, come there (don't get too loud, and nobody's feelings get hurt…) Located next to the Austrian and Belgian embassies, lots of coffee shops nearby. Great place for cool spiritual stopover on your way to the city center in summers and convernient, spiritual in all times for a prayer during e.g. a lunch break.
