The image is a blackboard with two illustrations on it. On the left side of the board, there is a diagram of a small shrine with a single room, dating from the 15th century BC. The shrine is made up of a series of small stones arranged in a grid-like pattern. The stones are of different sizes and shapes, with some being larger and others being smaller. 

On the right side, there are two illustrations of the shrine, one in white and one in black. The first illustration shows the shrine with the stone walls and the other in black and white. The text on the board provides further information about the shrine and its significance.

The background of the blackboard is a brick wall, and the text is written in white.
