The image shows an old, dilapidated stone structure in a museum. The structure appears to be made of large, irregularly shaped stones and is located in a large room with a high ceiling and large windows on the right side. The walls are made of stone and there is a metal railing in front of the structure. In the center of the image, there is an arch-like structure with a small opening at the bottom. The stone walls are stacked on top of each other and there are stairs leading up to the entrance. The floor is made of concrete and the overall appearance is one of decay and neglect.
