Sant Jordi 2025: books, roses, and author queues in Barcelona

Published on April 24, 2026 | Translated from Spanish

Authors and readers reunited in Barcelona during the celebration of Sant Jordi, an event that the herald Ali Smith described as a dream. The streets of the Catalan capital were filled with books and roses, with long queues in front of writers such as Regina Rodríguez Sirvent, Pedro Almodóvar, David Uclés, and Eduardo Mendoza. A day that combined tradition and literary passion. 📚

The queue algorithm: how to manage demand in real time ⚙️

Crowd management during Sant Jordi poses a technical challenge similar to that of a server under peak traffic. Queues in front of popular authors require an efficient prioritization system, similar to a FIFO or LIFO queue algorithm. Organizers use real-time monitoring tools to avoid bottlenecks and distribute the flow of attendees. Data synchronization between signing points and the official app allows adjusting routes and waiting times, minimizing pedestrian congestion.

The drama of choosing between a signed book and a wilted rose 🌹

While readers queued for hours to get a dedication from Almodóvar, others wondered if the signed book was worth more than the rose that was already starting to wilt in their hand. Some, more pragmatic, used their phones to calculate if the wait was worthwhile in terms of Instagram likes. In the end, the decision boiled down to a simple equation: how many minutes of your life are you willing to lose for a signature that you will later sell on Wallapop?
