In the Puerta del Sol area, a unique display of plants has appeared, bringing a touch of green to the otherwise gray space. The plants, which vary in size and texture, are a notable addition to the area. They can be found in a specific location, near a metro stop.

The plants are part of a promotional effort for a cerveza, or beer. Further details about this initiative are available from the source.
