Construction of Royal Road

6th century BCE

The Royal Road was an ancient highway of the Achaemenid Persian Empire, built by Darius I to improve communication across his vast territory, connecting the city of Susa in Persia to Sardis in western Anatolia over a distance of about 2,700 kilometres. The Greek historian Herodotus described the road, with its many staging posts at which royal messengers could exchange tired horses for fresh ones, and he is said to have written that neither snow nor rain nor heat nor darkness stopped these couriers. The journey took a traveller about three months on foot, but royal messengers could do it in a week. The road was used by armies, merchants and officials, and later by Alexander the Great.
