The Royal Road was a 2,699 km paved highway connecting Susa (administrative capital) to Sardis (Lydia). With 111 relay stations where couriers changed horses, messages traveled at astonishing speed across the empire.
Fun Facts
Herodotus wrote: "Neither snow nor rain nor heat nor gloom of night stays these couriers"—this phrase later became the motto of the US Postal Service! Regular travelers needed 90 days for this journey, but Chapars completed it in 7 days. This system inspired the later Silk Road.
