What is the logo of the underground hotel?

On maps or signboards, hotels, restaurants and hotels are usually represented by sleeping icons or similar patterns located at the lower part of the picture.

But there are few specific icons in the square, because the square is usually a large open space on the map, and most maps only mark words on the open space. However, because there are usually historical sites, landmark buildings or museums, churches, gymnasiums and other facilities around the square, some tourist maps and guide maps will mark the square with simplified patterns of these historical sites, landmark buildings or museums, similar to the small icons in the upper right corner of the attached drawings.
