The "Quiet Nest" villa is part of the Balchik palace. The top of the tower that looks like a mosque minaret has a built-in Aeolian harp whose strings play soft sounds on the wind. The palace complex consists of a number of residential villas, a smoking hall, a wine cellar, a power station, a monastery, a holy spring, a chapel and many other buildings, as well as most notably a park that is today a state-run botanical garden at the Black sea coast.
