50 Lei Old Orhei

Old Orhei is an archaeological and natural complex in central Moldova occupying a bend of the Răut River, where settlement layers run from Geto-Dacian through Mongol Golden Horde, Moldavian medieval, and Ottoman periods — an unusually compressed stratigraphic record for the region. The National Bank of Moldova has issued commemorative silver pieces tied to sites of national cultural significance since the late 1990s, and Old Orhei was an early and recurring subject given its status as the country's most prominent archaeological reserve.

The cave monastery carved into the limestone cliffs there dates to the 13th or 14th century and remains in active religious use.
