caption: The image shows a drawing of a castle in the middle of a body of water, with a few people, poles, and other objects in the foreground. The drawing is on a piece of paper, and is believed to be from the 17th century. The castle is surrounded by a lush landscape, with trees and mountains in the background. The sky is a deep blue, and the water is a light blue-green. The people in the drawing are wearing traditional clothing and appear to be looking out towards the castle.
