The Czernin Palace is the largest of the baroque palaces of Prague, which has served as the offices of the Czechoslovak and later Czech foreign ministry since the 1930s. It was commissioned by the diplomat Humprecht Jan Czernin, the Habsburg imperial ambassador to Venice and Rome, in the 1660s.
The palace features stuccos by Italian artists.
