The Biserica Doamnei church is a bit hard to find, but it's worth it to experience this oasis of peace and quiet in the heart of busy Bucharest. Locals usually arrive there at noon to say a prayer and leave a candle. It was built in 1683 by the Prince at the time and the entryway features some truly beautiful floral motifs. The interior is dark, small and intimate, and actually very cool on hot summer days. Strangely, Calea Victoriei is one of the liveliest streets in the city, with traffic, people running and shouting, and it's so funny to find complete serenity in the churchyard. The church is open every day until 5:00 pm excepts for weekends when it's open until 3:00.
