over 400,000 kms of roads connected the roman empire and it’s amazing that many of them still survive to this day. famously straight and featuring big slabs of polished rock, they were used for centuries to move troops around, trade goods, spread messages quickly… and even transport the animals that would fight humans and each other in the colosseum.

it’s fun to spot them throughout europe. the ones above are in rome, while the one below is in italica (near seville)… and yet, they look remarkably similar, despite being over 2000km apart.

it’s quite a feat of engineering!
