The image is a photograph of a black sign with white text and a pink hashtag symbol. The sign is located in a grassy area with trees in the background. The text on the sign reads "Hadrian's Wall" and "Brunton Turret". Below the hashtag, there is a brief description of Hadrian's wall, which was built by the order of the Emperor Hadrian, following his visit to Britain in AD 1222. It was planned as a continuous wall with a milestone every Roman mile (1.48 kilometers) and two turrets equally spaced between each fort. The wall, with its defensive ditches and large fortifications, stretched from coast to coast, a distance of 80 km/h.
