Did you know that in a drawing from the Berchholz collection, the author depicted nine light axes on the facade of the palace, that is, nine windows? On the first floor, one window replaces the front door. But if you look at other drawings and photographs of the southern facade of the palace, you will notice that there are only eight light axes. This is the author’s mistake. Why did it happen? The artist simply confused the southern and northern facades of the palace, as he painted from memory. After all, the Summer Palace has different facades. The southern façade has eight light axes, and the northern façade has nine.
