Abstract
This short note presents preliminary findings on the impact of the October 2024 floods on cultural heritage sites in Valencia, Spain.

We identify that 3.3% of heritage sites in the region have been potentially impacted, with churches and shrines (81), outdoor religious iconography (78), and historic irrigation features (45) being the most heavily affected. Our analysis utilizes data from OpenStreetMap and listings from the Generalitat Valenciana, suggesting that while OpenStreetMap's crowd-sourced data can provide useful estimates of the proportion of impacted sites, it may not be suitable for a detailed damage assessment. By sharing this data openly, we aim to contribute to international efforts in preserving cultural heritage after the disaster and provide a…
