This church and monastery - perhaps the most strikingly beautiful in Bucharest - was built in 1724 at the insistence of a Greek monk, Ioanikie Stratonikeas. It is characterized by its beautiful stone and wood carvings, of which the finest are on the main doors. The courtyard outside (beautiful on a sunny afternoon) has a curious collection of tombstones dating from the 18th century, and you might often see skilled craftsmen working on restoring them.
