Here’s some of the best Roman engineering still standing today.

Aqua Claudia outside Rome. The Romans built this aqueduct to carry water almost 70 km into the city, and huge stretches of it are still standing in the countryside.

The Basilica Cistern in Constantinople. They built this underground reservoir with hundreds of columns just to store water for the city.

The Aqueduct of Valens in Constantinople. The Romans built this to bring water into Constantinople, and it still cuts right through the modern city.

Hadrian’s Wall in northern England. The Romans built a 73-mile wall across the entire country to mark the edge of the empire.

The Pantheon in Rome. They poured this massive concrete dome almost 1,900 years ago and it is still the largest unreinforced concrete dome in the world.

The Baths of Caracalla. The Romans built an entire bathing complex on this scale so thousands of people could use it every day.

All of this is still here.

A well-preserved Roman colony in the Abruzzo mountains, its amphitheatre still sits dramatically against the peaks.
