4Roman Aqueduct of Segovia

Spain’s Roman heritage is on full display in Segovia, where the aqueduct stands as one of the best-preserved Roman engineering feats in the world. 

Built in the first century AD, this colossal structure stretches for over 800 meters, with arches towering above the old town. The fact that it was constructed without mortar and still stands today is a testament to Roman precision and durability. The aqueduct isn’t just an ancient utility—it’s a dramatic centerpiece that defines Segovia and embodies the enduring legacy of Roman civilization in Spain.
