Medieval Bridge of La Puebla de Roda Monument · Isábena, La Ribagorza, Huesca Image of Isábena, not of the place itself. The Puente de la Luz is a medieval three-arch bridge that crosses the Isábena river opposite La Puebla de Roda, capital of the municipality of Isábena, in the Ribagorza of Huesca, on the way to San Esteban de Mall. La Puebla rises on a small hillock on the right bank of the river, and in 1964 it merged with neighbouring Roda de Isábena to form the present-day municipality, retaining the status of capital.
