The Church of the Three Hierarchs, the most distinctive church in Iasi, Romania. It was completed in the 1630s, and its exterior of patterned stone carving was once layered in gold. It now provides the resting place for the crypts of Alexandru Ioan Cuza (the prince who unified Wallachia and Romania in 1859) and Dimitrie Cantemir, the last native Moldavian Prince before the period of Phanariot Greek rule under the Ottomans (1711-1824).
