Walk west to the Rambla and stop near the Liceu. In 1841 Barcelona contracted Charles Lebon to provide public gas lighting; in 1842 gas began replacing the older oil lamps on the Rambla. That sounds like a technical footnote until you ask what lighting actually buys a city: time. The Institut del Teatre's history of this stretch notes that after the change people strolled here until around ten at night. Artificial light did not invent nightlife, but it changed how safely and comfortably central public space could remain socially active after sunset. Look up at today's completely different lighting system and resist the temptation to treat illumination as background. Every generation of the night depends on infrastructure most walkers only notice when it fails.
What is documented — and what is not
