The image is a photograph of a sign in a park. The sign is rectangular in shape and has a blue background with white text. On the left side of the sign, there is an illustration of a brick building with a red roof and a chimney. Next to the building, there are two smaller illustrations of a canal with a bridge over it. 

The sign also has a banner at the top that reads "Welcome to Harlech Castle Tunnel". Below the illustration, it has a list of information about the tunnel, including its location, amenities, and history. There is also a blue trash can on the right side and a stone building in the background. The park is well-maintained with green grass and trees.
