Aqueducts: The Romans built extensive aqueduct systems to transport water from distant sources into cities and towns.
Concrete: Roman concrete, or opus caementicium, was a groundbreaking invention that enabled the construction of enduring structures like the Pantheon and the Colosseum.
Roads: The Roman road network, spanning over 250,000 miles, facilitated efficient military movement, trade, and communication across the empire.
Arches: The use of arches in Roman architecture, seen in structures like the Colosseum and aqueducts, allowed for the construction of larger and more stable buildings and bridges.
Sewage Systems: The Cloaca Maxima in Rome, one of the world's earliest sewage systems, was instrumental in managing wastewater and maintaining urban sanitation.
Heating Systems (Hypocausts): The Romans developed the hypocaust system, an early form of central heating that circulated hot air beneath floors and through walls.
Urban Planning: Roman cities were meticulously planned with a grid layout, including streets, public spaces, and zoning for residential, commercial, and industrial areas.
Bridges: Roman engineers built durable bridges using stone and concrete, with designs that included arches to distribute weight efficiently.
