The lowest-value Italian coin depicts the Castel del Monte. This castle was probably built between 1240 and 1250 but it is likely that construction was never completed. The castle’s function continues to remain a mystery. The design of this coin is by Eugenio Driutti.
Euro coins and banknotes were introduced on 1 January 2002 in twelve countries. Today, the euro area has grown to include 18 countries. Euro coins feature a common design on one side. Also, the national side (reverse) of every coin includes a ring of 12 stars from the European Union flag. Each country has its own design for the national side of its coins.
