Cetățuia Monastery from Iași is an Orthodox monastery of monks, founded in the 17th century by the voivode Gheorghe Duca (1665-1666, 1668-1672 and 1678-1683). Situated on a high hill in the south of Iași, from where you can see a beautiful panorama of the city, Cetățuia Monastery dominates the landscape with its slender silhouette, guarded by an imposing tower and surrounded by a weathered stone wall.
