Porta Maggiore, Roman city gate in Esquilino district, Italy
The white travertine double archway features two ancient roads, Via Praenestina and Via Labicana, intersecting beneath its monumental structure.
Emperor Claudius constructed this gate in 52 AD to support two aqueducts, Aqua Claudia and Anio Novus, before its integration into the Aurelian Walls.
The gate displays Latin inscriptions honoring Emperors Claudius, Vespasian, and Titus for their contributions to Rome's water infrastructure system.
Visitors reach the gate through multiple public transportation options, including buses and trams that stop near this eastern entrance of ancient Rome.
A subterranean Neopythagorean basilica from the first century lies nearby, decorated with white stucco designs representing philosophical beliefs.

Stone arch bridges rank among the most durable structures in history. From Roman aqueducts in Spain to medieval river crossings in Central Europe, these constructions demonstrate the evolution of engineering over two millennia. The Pont du Gard in France once transported 20,000 cubic meters of water daily over 50 kilometers, while the Segovia Aqueduct in Spain was built without mortar. In Asia, stone bridges like the Marco Polo Bridge in China have connected trade routes for centuries. The Khaju Bridge in Isfahan functions simultaneously as a dam and public gathering space. These structures served multiple purposes: transport, water supply, and social meeting points. Many of these bridges and aqueducts remain in use today. They document various construction techniques, from Roman concrete vaults to Persian brick arch structures. The constructions have survived wars, earthquakes, and floods, remaining functional elements of modern infrastructure.
