This high-value Greek definitive features the historic stone arch bridge of Konitsa, an iconic 19th-century structure spanning the Aoös River in Epirus. Printed in a rich sepia tone, the design highlights the rugged mountainous landscape and the elegant single-arch engineering typical of traditional Greek craftsmanship. Issued in the mid-20th century, this 500-drachma denomination served as a premium-rate stamp and is sought after for its architectural theme and scenic engraving quality. A fine addition for collectors of Greek landscapes, bridges, and classic definitive series.
