The image shows a drawing of a stone building with a door in the middle of it, surrounded by walls and text. The building appears to be a gatehouse, with a large archway leading up to the entrance. The walls are made of stone and the door is made of brick. The text on the paper reads "Elevation and Sections of a Gate in Lincoln Castle".
