Velasco rarely included historical people in his landscapes, but in this case the Empress Carlota and her retinue are shown riding in the park.
One assumes that they would have ridden from Chapultepec Castle. In the background, far removed from the city, you can see the castle. The white, diagonal line running from the castle is the road that Maximilian ordered to connect the imperial residence with the city. That country road is today the skyscraper-lined Paseo de la Reforma.
