Roman aqueduct

Dating back to the 1st century AD, the aqueduct of Barcino (modern-day Barcelona) was built to meet the water needs of the new Roman colony: baths, fountains, wealthy households, and crafts. Stretching over 11 km from Montcada, it combined underground conduits with elevated arcades and remained in use until the Visigothic period. Today, only a few remains survive: a 20 m section with four arches built into a house on Plaça del Vuit de Març (discovered in 1988) and two reconstructed arches (1958) on Plaça Nova, marking the aqueduct’s entry point into the Roman city.
