The image is a photograph of a sign on the side of a building that reads "The Roman Fort Derventio". The sign is yellow in color and has a black background. On the left side of the sign, there is an illustration of a man on a white horse, wearing a blue helmet and holding a sword. He is riding on the back of the horse and appears to be in the middle of a battle. 

On the right side, there are several smaller illustrations of people on horseback, some of whom are engaged in battle. The illustrations are in black and white and are arranged in a grid-like pattern.

In the center of the image, there appears to have a map of the Roman fort, with various geographical features such as mountains, rivers, and cities labeled. The map is overlaid on top of the illustration, and there is a small green sign on a brick wall next to it. The sign also has a bicycle leaning against the wall.
