Hi! I'm curious about something I recently saw along the wall near the Rivers of America at Disneyland. It's very close to the Tom Sawyer raft entrance. If you look up from the wall, you are staring at the Haunted Mansion. There are red bricks, within a grey brick arch. (Some of the bricks of concrete smoothed over them.) Around the grey brick arch are the large grey bricks (different sizes). At the top of the grey brick arch, there is an off-square with the date (I assume) of 1764. No cast members seem to know the story. I have a picture, but I guess I can't attach a picture. (???? I'm new to this posting.) I love the stories of Disneyland attractions, etc, and wondered if anyone knew what it was for this one. Thank you!
